Add a pure open source nForce Ethernet driver, under BSDL. This driver was ported from OpenBSD by Shigeaki Tagashira <shigeaki@se.hiroshima-u.ac.jp> and posted at http://www.se.hiroshima-u.ac.jp/~shigeaki/software/freebsd-nfe.html It was additionally cleaned up by me. It is still a work-in-progress and thus is purposefully not in GENERIC. And it conflicts with nve(4), so only one should be loaded.

P5N32-SLI PREMIUM from ASUSTeK is known to have MSI/MSI-X issue such that nfe(4) does not work with MSI-X. When MSI-X support was introduced, I remember MCP55 controller worked without problems so the issue could be either PCI bridge or BIOS issue. But I also noticed snd_hda(4) disabled MSI on all MCP55 chipset so I'm still not sure this is generic issue of MCP55 chipset. If this was PCI bridge issue we would have added it to a system wide black-list table but it's not clear to me at this moment whether it was caused by either broken BIOS or silicon bug of MCP55 chipset. To workaround the issue, maintain a MSI/MSI-X black-list table in driver and lookup base board manufacturer and product name from the table before attempting to use MSI-X. If driver find an matching entry, nfe(4) will not use MSI/MSI-X and fall back on traditional INTx mode. This approach should be the last resort since it relies on smbios and if another instance of MSI/MSI-X breakage is reported with different maker/product, we may have to get the PCI bridge black-listed instead of adding an new entry.

When user_frac in the polling subsystem is low it is going to busy the CPU for too long period than necessary. Additively, interfaces are kept polled (in the tick) even if no more packets are available. In order to avoid such situations a new generic mechanism can be implemented in proactive way, keeping track of the time spent on any packet and fragmenting the time for any tick, stopping the processing as soon as possible. In order to implement such mechanism, the polling handler needs to change, returning the number of packets processed. While the intended logic is not part of this patch, the polling KPI is broken by this commit, adding an int return value and the new flag IFCAP_POLLING_NOCOUNT (which will signal that the return value is meaningless for the installed handler and checking should be skipped). Bump __FreeBSD_version in order to signal such situation. Reviewed by: emaste Sponsored by: Sandvine Incorporated

Don't fail on device attach if jumbo frame support was unsuccessful. Because nfe(4) hardware doesn't support SG on Rx path, supporting jumbo frame requires very large contiguous kernel memory(i.e. several mega bytes). In case of lack of contiguous kernel memory that allocation request may always fail. However nfe(4) can operate on normal sized MTU frames, so go ahead and just disable jumbo frame support. While I'm here add a new tunable "hw.nfe.jumbo_disable" to disable jumbo frame support. In nfe_poll, make sure to invoke correct Rx handler. Approved by: re (kensmith)

Add a pure open source nForce Ethernet driver, under BSDL. This driver was ported from OpenBSD by Shigeaki Tagashira <shigeaki@se.hiroshima-u.ac.jp> and posted at http://www.se.hiroshima-u.ac.jp/~shigeaki/software/freebsd-nfe.html It was additionally cleaned up by me. It is still a work-in-progress and thus is purposefully not in GENERIC. And it conflicts with nve(4), so only one should be loaded.

Don't fail on device attach if jumbo frame support was unsuccessful. Because nfe(4) hardware doesn't support SG on Rx path, supporting jumbo frame requires very large contiguous kernel memory(i.e. several mega bytes). In case of lack of contiguous kernel memory that allocation request may always fail. However nfe(4) can operate on normal sized MTU frames, so go ahead and just disable jumbo frame support. While I'm here add a new tunable "hw.nfe.jumbo_disable" to disable jumbo frame support. In nfe_poll, make sure to invoke correct Rx handler. Approved by: re (kensmith)

[1] o Add additional protections, missing Tx completion interrupt, losing start Tx command, for watchdog timeout. o Switch to taskqueue(9) API to handle interrupts. o Use our own timer for watchdog instead of if_watchdog/if_timer interface. o Advertise VLAN header length/capability correctly to upper layer. o Remove excessive kernel stack consumption in nfe_encap(). o Handle highly fragmented mbuf chains correctly. o Enable etherenet address reprogramming with ifconfig(8). o Add ALTQ/TSO, MSI/MSIX support. o Increased Rx ring to 256 descriptors from 128. o Align Tx/Rx descriptor ring on sizeof(struct nfe_desc64) boundary. o Remove alignment restrictions on Tx/Rx buffers. o Rewritten jumbo frame support code. o Add support for hardware assistend VLAN tag insertion/stripping. o Add support for Tx/Rx flow control based on patches from Peer Chen.

P5N32-SLI PREMIUM from ASUSTeK is known to have MSI/MSI-X issue such that nfe(4) does not work with MSI-X. When MSI-X support was introduced, I remember MCP55 controller worked without problems so the issue could be either PCI bridge or BIOS issue. But I also noticed snd_hda(4) disabled MSI on all MCP55 chipset so I'm still not sure this is generic issue of MCP55 chipset. If this was PCI bridge issue we would have added it to a system wide black-list table but it's not clear to me at this moment whether it was caused by either broken BIOS or silicon bug of MCP55 chipset. To workaround the issue, maintain a MSI/MSI-X black-list table in driver and lookup base board manufacturer and product name from the table before attempting to use MSI-X. If driver find an matching entry, nfe(4) will not use MSI/MSI-X and fall back on traditional INTx mode. This approach should be the last resort since it relies on smbios and if another instance of MSI/MSI-X breakage is reported with different maker/product, we may have to get the PCI bridge black-listed instead of adding an new entry.

Don't fail on device attach if jumbo frame support was unsuccessful. Because nfe(4) hardware doesn't support SG on Rx path, supporting jumbo frame requires very large contiguous kernel memory(i.e. several mega bytes). In case of lack of contiguous kernel memory that allocation request may always fail. However nfe(4) can operate on normal sized MTU frames, so go ahead and just disable jumbo frame support. While I'm here add a new tunable "hw.nfe.jumbo_disable" to disable jumbo frame support. In nfe_poll, make sure to invoke correct Rx handler. Approved by: re (kensmith)

MCP55 is the only NVIDIA controller that supports VLAN tag insertion/stripping and it also supports TSO over VLAN. Implement TSO over VLAN support for MCP55 controller. While I'm here clean up SIOCSIFCAP ioctl handler. Since nfe(4) sets ifp capabilities based on various hardware flags in device attach, there is no need to check hardware flags again in SIOCSIFCAP ioctl handler. Also fix a bug which toggled both TX and RX checksum offloading even if user requested either TX or RX checksum configuration change. Tested by: Rob Farmer ( rfarmer <> predatorlabs dot net )

Add basic WOL support for MCP ethernet controllers. It seems the controller does not perform automatic switching from 1000Mbps link to 10/100Mbps link when WOL is activated. Implement establishing 10/100Mps link with auto-negotiation in driver. Link status change handler was modified to remove taskqueue based approach since driver now needs synchronous handling for link establishment.

o Flesh out the generic IEEE 802.3 annex 31B full duplex flow control support in mii(4): - Merge generic flow control advertisement (which can be enabled by passing by MIIF_DOPAUSE to mii_attach(9)) and parsing support from NetBSD into mii_physubr.c and ukphy_subr.c. Unlike as in NetBSD, IFM_FLOW isn't implemented as a global option via the "don't care mask" but instead as a media specific option this. This has the following advantages: o allows flow control advertisement with autonegotiation to be turned on and off via ifconfig(8) with the default typically being off (though MIIF_FORCEPAUSE has been added causing flow control to be always advertised, allowing to easily MFC this changes for drivers that previously used home-grown support for flow control that behaved that way without breaking POLA) o allows to deal with PHY drivers where flow control advertisement with manual selection doesn't work or at least isn't implemented, like it's the case with brgphy(4), e1000phy(4) and ip1000phy(4), by setting MIIF_NOMANPAUSE o the available combinations of media options are readily available from the `ifconfig -m` output - Add IFM_FLOW to IFM_SHARED_OPTION_DESCRIPTIONS and IFM_ETH_RXPAUSE and IFM_ETH_TXPAUSE to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so these are understood by ifconfig(8). o Make the master/slave support in mii(4) actually usable: - Change IFM_ETH_MASTER from being implemented as a global option via the "don't care mask" to a media specific one as it actually is only applicable to IFM_1000_T to date. - Let mii_phy_setmedia() set GTCR_MAN_MS in IFM_1000_T slave mode to actually configure manually selected slave mode (like we also do in the PHY specific implementations). - Add IFM_ETH_MASTER to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so it is understood by ifconfig(8). o Switch bge(4), bce(4), msk(4), nfe(4) and stge(4) along with brgphy(4), e1000phy(4) and ip1000phy(4) to use the generic flow control support instead of home-grown solutions via IFM_FLAGs. This includes changing these PHY drivers and smcphy(4) to no longer unconditionally advertise support for flow control but only if the selected media has IFM_FLOW set (or MIIF_FORCEPAUSE is set) and implemented for these media variants, i.e. typically only for copper. o Switch brgphy(4), ciphy(4), e1000phy(4) and ip1000phy(4) to report and set IFM_1000_T master mode via IFM_ETH_MASTER instead of via IFF_LINK0 and some IFM_FLAGn. o Switch brgphy(4) to add at least the the supported copper media based on the contents of the BMSR via mii_phy_add_media() instead of hardcoding them. The latter approach seems to have developed historically, besides causing unnecessary code duplication it was also undesirable because brgphy_mii_phy_auto() already based the capability advertisement on the contents of the BMSR though. o Let brgphy(4) set IFM_1000_T master mode on all supported PHY and not just BCM5701. Apparently this was a misinterpretation of a workaround in the Linux tg3 driver; BCM5701 seem to require RGPHY_1000CTL_MSE and BRGPHY_1000CTL_MSC to be set when configuring autonegotiation but this doesn't mean we can't set these as well on other PHYs for manual media selection. o Let ukphy_status() report IFM_1000_T master mode via IFM_ETH_MASTER so IFM_1000_T master mode support now is generally available with all PHY drivers. o Don't let e1000phy(4) set master/slave bits for IFM_1000_SX as it's not applicable there.

Add a pure open source nForce Ethernet driver, under BSDL. This driver was ported from OpenBSD by Shigeaki Tagashira <shigeaki@se.hiroshima-u.ac.jp> and posted at http://www.se.hiroshima-u.ac.jp/~shigeaki/software/freebsd-nfe.html It was additionally cleaned up by me.

P5N32-SLI PREMIUM from ASUSTeK is known to have MSI/MSI-X issue such that nfe(4) does not work with MSI-X. When MSI-X support was introduced, I remember MCP55 controller worked without problems so the issue could be either PCI bridge or BIOS issue. But I also noticed snd_hda(4) disabled MSI on all MCP55 chipset so I'm still not sure this is generic issue of MCP55 chipset. If this was PCI bridge issue we would have added it to a system wide black-list table but it's not clear to me at this moment whether it was caused by either broken BIOS or silicon bug of MCP55 chipset. To workaround the issue, maintain a MSI/MSI-X black-list table in driver and lookup base board manufacturer and product name from the table before attempting to use MSI-X. If driver find an matching entry, nfe(4) will not use MSI/MSI-X and fall back on traditional INTx mode. This approach should be the last resort since it relies on smbios and if another instance of MSI/MSI-X breakage is reported with different maker/product, we may have to get the PCI bridge black-listed instead of adding an new entry.

Add a pure open source nForce Ethernet driver, under BSDL. This driver was ported from OpenBSD by Shigeaki Tagashira <shigeaki@se.hiroshima-u.ac.jp> and posted at http://www.se.hiroshima-u.ac.jp/~shigeaki/software/freebsd-nfe.html It was additionally cleaned up by me. It is still a work-in-progress and thus is purposefully not in GENERIC. And it conflicts with nve(4), so only one should be loaded.

Add a pure open source nForce Ethernet driver, under BSDL. This driver was ported from OpenBSD by Shigeaki Tagashira <shigeaki@se.hiroshima-u.ac.jp> and posted at http://www.se.hiroshima-u.ac.jp/~shigeaki/software/freebsd-nfe.html It was additionally cleaned up by me. It is still a work-in-progress and thus is purposefully not in GENERIC. And it conflicts with nve(4), so only one should be loaded.

Bring overhauled nfe(4) into tree. o s/printf/device_printf/g o Nuke OpenBSDism. o Nuke NetBSD/OpenBSD specific DMA sync operations.(we don't have a way to sync a single descriptor within a DMA map.) o Remove recursive mutex. o bus_dma(9) clean up. o 40bit DMA address support. o Add protection for Rx map load failure. o Fix a long standing bug for watchdog timeout. [1] o Add additional protections, missing Tx completion interrupt, losing start Tx command, for watchdog timeout. o Switch to taskqueue(9) API to handle interrupts. o Use our own timer for watchdog instead of if_watchdog/if_timer interface. o Advertise VLAN header length/capability correctly to upper layer. o Remove excessive kernel stack consumption in nfe_encap(). o Handle highly fragmented mbuf chains correctly. o Enable etherenet address reprogramming with ifconfig(8). o Add ALTQ/TSO, MSI/MSIX support. o Increased Rx ring to 256 descriptors from 128. o Align Tx/Rx descriptor ring on sizeof(struct nfe_desc64) boundary. o Remove alignment restrictions on Tx/Rx buffers. o Rewritten jumbo frame support code. o Add support for hardware assistend VLAN tag insertion/stripping. o Add support for Tx/Rx flow control based on patches from Peer Chen.

This includes changing these PHY drivers and smcphy(4) to no longer unconditionally advertise support for flow control but only if the selected media has IFM_FLOW set (or MIIF_FORCEPAUSE is set) and implemented for these media variants, i.e. typically only for copper. o Switch brgphy(4), ciphy(4), e1000phy(4) and ip1000phy(4) to report and set IFM_1000_T master mode via IFM_ETH_MASTER instead of via IFF_LINK0 and some IFM_FLAGn. o Switch brgphy(4) to add at least the the supported copper media based on the contents of the BMSR via mii_phy_add_media() instead of hardcoding them. The latter approach seems to have developed historically, besides causing unnecessary code duplication it was also undesirable because brgphy_mii_phy_auto() already based the capability advertisement on the contents of the BMSR though. o Let brgphy(4) set IFM_1000_T master mode on all supported PHY and not just BCM5701. Apparently this was a misinterpretation of a workaround in the Linux tg3 driver; BCM5701 seem to require RGPHY_1000CTL_MSE and BRGPHY_1000CTL_MSC to be set when configuring autonegotiation but this doesn't mean we can't set these as well on other PHYs for manual media selection. o Let ukphy_status() report IFM_1000_T master mode via IFM_ETH_MASTER so IFM_1000_T master mode support now is generally available with all PHY drivers. o Don't let e1000phy(4) set master/slave bits for IFM_1000_SX as it's not applicable there.

Don't fail on device attach if jumbo frame support was unsuccessful. Because nfe(4) hardware doesn't support SG on Rx path, supporting jumbo frame requires very large contiguous kernel memory(i.e. several mega bytes). In case of lack of contiguous kernel memory that allocation request may always fail. However nfe(4) can operate on normal sized MTU frames, so go ahead and just disable jumbo frame support. While I'm here add a new tunable "hw.nfe.jumbo_disable" to disable jumbo frame support. In nfe_poll, make sure to invoke correct Rx handler. Approved by: re (kensmith)

Don't fail on device attach if jumbo frame support was unsuccessful. Because nfe(4) hardware doesn't support SG on Rx path, supporting jumbo frame requires very large contiguous kernel memory(i.e. several mega bytes). In case of lack of contiguous kernel memory that allocation request may always fail. However nfe(4) can operate on normal sized MTU frames, so go ahead and just disable jumbo frame support. While I'm here add a new tunable "hw.nfe.jumbo_disable" to disable jumbo frame support. In nfe_poll, make sure to invoke correct Rx handler. Approved by: re (kensmith)

Nuke local jumbo allocator and switch to use of UMA backed page allocator for jumbo frame. Also remove unneeded jlist lock which is no longer required to protect jumbo buffers. With these changes jumbo frame performance of nfe(4) was slightly increased and users should not encounter jumbo buffer allocation failure anymore.

Don't fail on device attach if jumbo frame support was unsuccessful. Because nfe(4) hardware doesn't support SG on Rx path, supporting jumbo frame requires very large contiguous kernel memory(i.e. several mega bytes). In case of lack of contiguous kernel memory that allocation request may always fail. However nfe(4) can operate on normal sized MTU frames, so go ahead and just disable jumbo frame support. While I'm here add a new tunable "hw.nfe.jumbo_disable" to disable jumbo frame support. In nfe_poll, make sure to invoke correct Rx handler. Approved by: re (kensmith)

When user_frac in the polling subsystem is low it is going to busy the CPU for too long period than necessary. Additively, interfaces are kept polled (in the tick) even if no more packets are available. In order to avoid such situations a new generic mechanism can be implemented in proactive way, keeping track of the time spent on any packet and fragmenting the time for any tick, stopping the processing as soon as possible. In order to implement such mechanism, the polling handler needs to change, returning the number of packets processed. While the intended logic is not part of this patch, the polling KPI is broken by this commit, adding an int return value and the new flag IFCAP_POLLING_NOCOUNT (which will signal that the return value is meaningless for the installed handler and checking should be skipped). Bump __FreeBSD_version in order to signal such situation. Reviewed by: emaste Sponsored by: Sandvine Incorporated

Don't fail on device attach if jumbo frame support was unsuccessful. Because nfe(4) hardware doesn't support SG on Rx path, supporting jumbo frame requires very large contiguous kernel memory(i.e. several mega bytes). In case of lack of contiguous kernel memory that allocation request may always fail. However nfe(4) can operate on normal sized MTU frames, so go ahead and just disable jumbo frame support. While I'm here add a new tunable "hw.nfe.jumbo_disable" to disable jumbo frame support. In nfe_poll, make sure to invoke correct Rx handler. Approved by: re (kensmith)

Add basic WOL support for MCP ethernet controllers. It seems the controller does not perform automatic switching from 1000Mbps link to 10/100Mbps link when WOL is activated. Implement establishing 10/100Mps link with auto-negotiation in driver. Link status change handler was modified to remove taskqueue based approach since driver now needs synchronous handling for link establishment.

During boot(before setting IP address) PHY can generate link state change interrupt if the link is established with link parter. However interrupt handler didn't acknowledge the interrupt if nfe(4) was not running at the time of interrupt delivery. This caused endless interrupt generation. Fix the bug by acknowledging the interrupt regardless of running state of the driver. PR: kern/116295 Submitted by: Mark Derbyshire (mark At taom dot com) Approved by: re (kensmith)

When user_frac in the polling subsystem is low it is going to busy the CPU for too long period than necessary. Additively, interfaces are kept polled (in the tick) even if no more packets are available. In order to avoid such situations a new generic mechanism can be implemented in proactive way, keeping track of the time spent on any packet and fragmenting the time for any tick, stopping the processing as soon as possible. In order to implement such mechanism, the polling handler needs to change, returning the number of packets processed. While the intended logic is not part of this patch, the polling KPI is broken by this commit, adding an int return value and the new flag IFCAP_POLLING_NOCOUNT (which will signal that the return value is meaningless for the installed handler and checking should be skipped).

Add a pure open source nForce Ethernet driver, under BSDL. This driver was ported from OpenBSD by Shigeaki Tagashira <shigeaki@se.hiroshima-u.ac.jp> and posted at http://www.se.hiroshima-u.ac.jp/~shigeaki/software/freebsd-nfe.html It was additionally cleaned up by me. It is still a work-in-progress and thus is purposefully not in GENERIC. And it conflicts with nve(4), so only one should be loaded.

When user_frac in the polling subsystem is low it is going to busy the CPU for too long period than necessary. Additively, interfaces are kept polled (in the tick) even if no more packets are available. In order to avoid such situations a new generic mechanism can be implemented in proactive way, keeping track of the time spent on any packet and fragmenting the time for any tick, stopping the processing as soon as possible. In order to implement such mechanism, the polling handler needs to change, returning the number of packets processed. While the intended logic is not part of this patch, the polling KPI is broken by this commit, adding an int return value and the new flag IFCAP_POLLING_NOCOUNT (which will signal that the return value is meaningless for the installed handler and checking should be skipped).

When user_frac in the polling subsystem is low it is going to busy the CPU for too long period than necessary. Additively, interfaces are kept polled (in the tick) even if no more packets are available. In order to avoid such situations a new generic mechanism can be implemented in proactive way, keeping track of the time spent on any packet and fragmenting the time for any tick, stopping the processing as soon as possible. In order to implement such mechanism, the polling handler needs to change, returning the number of packets processed. While the intended logic is not part of this patch, the polling KPI is broken by this commit, adding an int return value and the new flag IFCAP_POLLING_NOCOUNT (which will signal that the return value is meaningless for the installed handler and checking should be skipped).

This driver was ported from OpenBSD by Shigeaki Tagashira <shigeaki@se.hiroshima-u.ac.jp> and posted at http://www.se.hiroshima-u.ac.jp/~shigeaki/software/freebsd-nfe.html It was additionally cleaned up by me. It is still a work-in-progress and thus is purposefully not in GENERIC. And it conflicts with nve(4), so only one should be loaded.

Bring overhauled nfe(4) into tree. o s/printf/device_printf/g o Nuke OpenBSDism. o Nuke NetBSD/OpenBSD specific DMA sync operations.(we don't have a way to sync a single descriptor within a DMA map.) o Remove recursive mutex. o bus_dma(9) clean up. o 40bit DMA address support. o Add protection for Rx map load failure. o Fix a long standing bug for watchdog timeout. [1] o Add additional protections, missing Tx completion interrupt, losing start Tx command, for watchdog timeout. o Switch to taskqueue(9) API to handle interrupts. o Use our own timer for watchdog instead of if_watchdog/if_timer interface. o Advertise VLAN header length/capability correctly to upper layer. o Remove excessive kernel stack consumption in nfe_encap(). o Handle highly fragmented mbuf chains correctly. o Enable etherenet address reprogramming with ifconfig(8). o Add ALTQ/TSO, MSI/MSIX support. o Increased Rx ring to 256 descriptors from 128. o Align Tx/Rx descriptor ring on sizeof(struct nfe_desc64) boundary. o Remove alignment restrictions on Tx/Rx buffers. o Rewritten jumbo frame support code. o Add support for hardware assistend VLAN tag insertion/stripping. o Add support for Tx/Rx flow control based on patches from Peer Chen. [2] o Add a routine that detects whether ethernet address swap routines is required. [3] o Add a workaround that take MAC/PHY out of power down mode. o Add suspend/resume support. o style(9) and code clean up. Special thanks to Shigeaki Tagashira, the original porter of nfe(4), who submitted lots of patches, performed uncountable number of regression tests and maintained nfe(4) for a long time. Without his enthusiastic help and support I could never have completed this overhauling task. The only weak point of nfe(4) compared to nve(4) is instability of manual half-duplex media selection on certain hardwares(auto sensing media type should work for all cases, though). This was a long standing bug of nfe(4) and I still have no idea why it doesn't work on some hardwares.

When user_frac in the polling subsystem is low it is going to busy the CPU for too long period than necessary. Additively, interfaces are kept polled (in the tick) even if no more packets are available. In order to avoid such situations a new generic mechanism can be implemented in proactive way, keeping track of the time spent on any packet and fragmenting the time for any tick, stopping the processing as soon as possible. In order to implement such mechanism, the polling handler needs to change, returning the number of packets processed. While the intended logic is not part of this patch, the polling KPI is broken by this commit, adding an int return value and the new flag IFCAP_POLLING_NOCOUNT (which will signal that the return value is meaningless for the installed handler and checking should be skipped). Bump __FreeBSD_version in order to signal such situation. Reviewed by: emaste Sponsored by: Sandvine Incorporated

Add basic WOL support for MCP ethernet controllers. It seems the controller does not perform automatic switching from 1000Mbps link to 10/100Mbps link when WOL is activated. Implement establishing 10/100Mps link with auto-negotiation in driver. Link status change handler was modified to remove taskqueue based approach since driver now needs synchronous handling for link establishment. Submitted by: Yamagi Burmeister (lists <> yamagi.org ) (initial version) Tested by: Yamagi Burmeister (lists <> yamagi.org ) MFC after: 1 week

Bring overhauled nfe(4) into tree. o s/printf/device_printf/g o Nuke OpenBSDism. o Nuke NetBSD/OpenBSD specific DMA sync operations.(we don't have a way to sync a single descriptor within a DMA map.) o Remove recursive mutex. o bus_dma(9) clean up. o 40bit DMA address support. o Add protection for Rx map load failure. o Fix a long standing bug for watchdog timeout. [1] o Add additional protections, missing Tx completion interrupt, losing start Tx command, for watchdog timeout. o Switch to taskqueue(9) API to handle interrupts. o Use our own timer for watchdog instead of if_watchdog/if_timer interface. o Advertise VLAN header length/capability correctly to upper layer. o Remove excessive kernel stack consumption in nfe_encap(). o Handle highly fragmented mbuf chains correctly. o Enable etherenet address reprogramming with ifconfig(8). o Add ALTQ/TSO, MSI/MSIX support. o Increased Rx ring to 256 descriptors from 128. o Align Tx/Rx descriptor ring on sizeof(struct nfe_desc64) boundary. o Remove alignment restrictions on Tx/Rx buffers. o Rewritten jumbo frame support code. o Add support for hardware assistend VLAN tag insertion/stripping. o Add support for Tx/Rx flow control based on patches from Peer Chen.

This driver was ported from OpenBSD by Shigeaki Tagashira <shigeaki@se.hiroshima-u.ac.jp> and posted at http://www.se.hiroshima-u.ac.jp/~shigeaki/software/freebsd-nfe.html It was additionally cleaned up by me. It is still a work-in-progress and thus is purposefully not in GENERIC. And it conflicts with nve(4), so only one should be loaded.

Bring overhauled nfe(4) into tree. o s/printf/device_printf/g o Nuke OpenBSDism. o Nuke NetBSD/OpenBSD specific DMA sync operations.(we don't have a way to sync a single descriptor within a DMA map.) o Remove recursive mutex. o bus_dma(9) clean up. o 40bit DMA address support. o Add protection for Rx map load failure. o Fix a long standing bug for watchdog timeout. [1] o Add additional protections, missing Tx completion interrupt, losing start Tx command, for watchdog timeout. o Switch to taskqueue(9) API to handle interrupts. o Use our own timer for watchdog instead of if_watchdog/if_timer interface. o Advertise VLAN header length/capability correctly to upper layer. o Remove excessive kernel stack consumption in nfe_encap(). o Handle highly fragmented mbuf chains correctly. o Enable etherenet address reprogramming with ifconfig(8). o Add ALTQ/TSO, MSI/MSIX support. o Increased Rx ring to 256 descriptors from 128. o Align Tx/Rx descriptor ring on sizeof(struct nfe_desc64) boundary. o Remove alignment restrictions on Tx/Rx buffers. o Rewritten jumbo frame support code. o Add support for hardware assistend VLAN tag insertion/stripping. o Add support for Tx/Rx flow control based on patches from Peer Chen.

Special thanks to Shigeaki Tagashira, the original porter of nfe(4), who submitted lots of patches, performed uncountable number of regression tests and maintained nfe(4) for a long time. Without his enthusiastic help and support I could never have completed this overhauling task.

Implement establishing 10/100Mps link with auto-negotiation in driver. Link status change handler was modified to remove taskqueue based approach since driver now needs synchronous handling for link establishment.

Add a pure open source nForce Ethernet driver, under BSDL. This driver was ported from OpenBSD by Shigeaki Tagashira <shigeaki@se.hiroshima-u.ac.jp> and posted at http://www.se.hiroshima-u.ac.jp/~shigeaki/software/freebsd-nfe.html It was additionally cleaned up by me. It is still a work-in-progress and thus is purposefully not in GENERIC. And it conflicts with nve(4), so only one should be loaded.

Add basic WOL support for MCP ethernet controllers. It seems the controller does not perform automatic switching from 1000Mbps link to 10/100Mbps link when WOL is activated. Implement establishing 10/100Mps link with auto-negotiation in driver. Link status change handler was modified to remove taskqueue based approach since driver now needs synchronous handling for link establishment.
