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.

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 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.

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 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).

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.

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).

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 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. 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.

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).
