This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

* The SysKonnect gigabit ethernet adapters consist of two main
* components: the SysKonnect GEnesis controller chip and the XaQti Corp.
* XMAC II gigabit ethernet MAC. The XMAC provides all of the MAC
* components and a PHY while the GEnesis controller provides a PCI
* interface with DMA support. Each card may have between 512K and
* 2MB of SRAM on board depending on the configuration.
*
* The SysKonnect GEnesis controller can have either one or two XMAC
* chips connected to it, allowing single or dual port NIC configurations.
* SysKonnect has the distinction of being the only vendor on the market
* with a dual port gigabit ethernet NIC. The GEnesis provides dual FIFOs,
* dual DMA queues, packet/MAC/transmit arbiters and direct access to the
* XMAC registers. This driver takes advantage of these features to allow
* both XMACs to operate as independent interfaces.

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames.

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC.

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine.

I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon.

Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command.

Replace the mbuf external reference counting code with something that should be better. The old code counted references to mbuf clusters by using the offset of the cluster from the start of memory allocated for mbufs and clusters as an index into an array of chars, which did the reference counting. If the external storage was not a cluster then reference counting had to be done by the code using that external storage. NetBSD's system of linked lists of mbufs was cosidered, but Alfred felt it would have locking issues when the kernel was made more SMP friendly. The system implimented uses a pool of unions to track external storage. The union contains an int for counting the references and a pointer for forming a free list. The reference counts are incremented and decremented atomically and so should be SMP friendly. This system can track reference counts for any sort of external storage. Access to the reference counting stuff is now through macros defined in mbuf.h, so it should be easier to make changes to the system in the future. The possibility of storing the reference count in one of the referencing mbufs was considered, but was rejected 'cos it would often leave extra mbufs allocated. Storing the reference count in the cluster was also considered, but because the external storage may not be a cluster this isn't an option. The size of the pool of reference counters is available in the stats provided by "netstat -m".

This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames.

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames.

Clean up locking and resource management for pci/if_* - Remove locking of the softc in the attach method, instead depending on bus_setup_intr being at the end of attach (delaying interrupt enable until after ether_ifattach is called) - Call *_detach directly in the error case of attach, depending on checking in detach to only free resources that were allocated. This puts all resource freeing in one place, avoiding thinkos that lead to memory leaks. - Add bus_child_present check to calls to *_stop in the detach method to be sure hw is present before touching its registers. - Remove bzero softc calls since device_t should do this for us. - dc: move interrupt allocation back where it was before. It was unnecessary to move it. This reverts part of 1.88 - rl: move irq allocation before ether_ifattach. Problems might have been caused by allocating the irq after enabling interrupts on the card. - rl: call rl_stop before ether_ifdetach - sf: call sf_stop before ether_ifdetach - sis: add missed free of sis_tag - sis: check errors from tag creation - sis: move dmamem_alloc and dmamap_load to happen at same time as tag creation - sk: remove duplicate initialization of sk_dev - ste: add missed bus_generic_detach - ti: call ti_stop before ether_ifdetach - ti: add missed error setting in ti_rdata alloc failure - vr: add missed error setting in I/O, memory mapping cases - xl: add missed error setting in I/O, memory mapping cases - xl: remove multi-level goto on attach failure - xl: move dmamem_alloc and dmamap_load to happen at same time as tag creation - Calls to free(9) are unconditional because it is valid to call free with a null pointer.

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters.

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames.

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data.

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames.

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames.

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC. It seems that there is still occasional watchdog timeout error but I couldn't reproduce it and need more information to analyze it from users.

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it.

As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

Previously it passed corrupted packets to upper layers under certain conditions. - A new function sk_yukon_tick() to handle auto-negotiation properly. - Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress. - suspend/resume support(not tested). - Added Rx/Tx FIFO flush routine for Yukon - Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command. - s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc. - Setting multicast/station address is now safe on strict-alignment architectures. - Fix long standing bug in VLAN header length setup. - Added/corrected register definitions for Yukon. (Register information from Linux skge driver.) - Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.) - Update if_oerrors if we encounter watchdog error. - callout(9) conversion Special thanks to jkim who let me know RX status differences between Yukon and XaQti XMAC.

This commit adds driver support for the SysKonnect SK-984x series gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).

Bring busdmafied sk(4) to all architectures. - MPSAFE. No more recursive lock required. - bus_dma(9) conversion. I think it should work on all architectures. - optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling. - Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first. - Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal. - Added an additional lock for MII register access callbacks. - Added more strict received packet validation routine.
