Add alc(4), a driver for Atheros AR8131/AR8132 PCIe ethernet controller. These controllers are also known as L1C(AR8131) and L2C(AR8132) respectively. These controllers resembles the first generation controller L1 but usage of different descriptor format and new register mappings over L1 register space requires a new driver. There are a couple of registers I still don't understand but the driver seems to have no critical issues for performance and stability. Currently alc(4) supports the following hardware features. o MSI o TCP Segmentation offload o Hardware VLAN tag insertion/stripping o Tx/Rx interrupt moderation o Hardware statistics counters(dev.alc.%d.stats) o Jumbo frame o WOL AR8131/AR8132 also supports Tx checksum offloading but I disabled it due to stability issues. I'm not sure this comes from broken sample boards or hardware bugs. If you know your controller works without problems you can still enable it. The controller has a silicon bug for Rx checksum offloading, so the feature was not implemented. I'd like to say big thanks to Atheros. Atheros kindly sent sample boards to me and answered several questions I had. HW donated by: Atheros Communications, Inc.

For AR8132 fast ethernet controller, do not report 1000baseT capability to mii(4). Even though AR8132 uses the same model/ revision number of F1 gigabit PHY, the PHY has no ability to establish 1000baseT link. I have no idea why Atheros use the same device/model id for this PHY. With this change atphy(4) does not report 1000baseT media capability and manual 1000baseT configuration is also disabled which is more desirable behavior for 10/100Mbps PHY.

Add alc(4), a driver for Atheros AR8131/AR8132 PCIe ethernet controller. These controllers are also known as L1C(AR8131) and L2C(AR8132) respectively. These controllers resembles the first generation controller L1 but usage of different descriptor format and new register mappings over L1 register space requires a new driver. There are a couple of registers I still don't understand but the driver seems to have no critical issues for performance and stability. Currently alc(4) supports the following hardware features. o MSI o TCP Segmentation offload o Hardware VLAN tag insertion/stripping o Tx/Rx interrupt moderation o Hardware statistics counters(dev.alc.%d.stats) o Jumbo frame o WOL AR8131/AR8132 also supports Tx checksum offloading but I disabled it due to stability issues. I'm not sure this comes from broken sample boards or hardware bugs. If you know your controller works without problems you can still enable it. The controller has a silicon bug for Rx checksum offloading, so the feature was not implemented. I'd like to say big thanks to Atheros.

- Remove attempts to implement setting of BMCR_LOOP/MIIF_NOLOOP (reporting IFM_LOOP based on BMCR_LOOP is left in place though as it might provide useful for debugging). For most mii(4) drivers it was unclear whether the PHYs driven by them actually support loopback or not. Moreover, typically loopback mode also needs to be activated on the MAC, which none of the Ethernet drivers using mii(4) implements. Given that loopback media has no real use (and obviously hardly had a chance to actually work) besides for driver development (which just loopback mode should be sufficient for though, i.e one doesn't necessary need support for loopback media) support for it is just dropped as both NetBSD and OpenBSD already did quite some time ago. - Let mii_phy_add_media() also announce the support of IFM_NONE. - Restructure the PHY entry points to use a structure of entry points instead of discrete function pointers, and extend this to include a "reset" entry point. Make sure any PHY-specific reset routine is always used, and provide one for lxtphy(4) which disables MII interrupts (as is done for a few other PHYs we have drivers for). This includes changing NIC drivers which previously just called the generic mii_phy_reset() to now actually call the PHY-specific reset routine, which might be crucial in some cases. While at it, the redundant checks in these NIC drivers for mii->mii_instance not being zero before calling the reset routines were removed because as soon as one PHY driver attaches mii->mii_instance is incremented and we hardly can end up in their media change callbacks etc if no PHY driver has attached as mii_attach() would have failed in that case and not attach a miibus(4) instance. Consequently, NIC drivers now no longer should call mii_phy_reset() directly, so it was removed from EXPORT_SYMS. - Add a mii_phy_dev_attach() as a companion helper to mii_phy_dev_probe(). The purpose of that function is to perform the common steps to attach a PHY driver instance and to hook it up to the miibus(4) instance and to optionally also handle the probing, addition and initialization of the supported media. So all a PHY driver without any special requirements has to do in its bus attach method is to call mii_phy_dev_attach() along with PHY-specific MIIF_* flags, a pointer to its PHY functions and the add_media set to one. All PHY drivers were updated to take advantage of mii_phy_dev_attach() as appropriate. Along with these changes the capability mask was added to the mii_softc structure so PHY drivers taking advantage of mii_phy_dev_attach() but still handling media on their own do not need to fiddle with the MII attach arguments anyway. - Keep track of the PHY offset in the mii_softc structure. This is done for compatibility with NetBSD/OpenBSD. - Keep track of the PHY's OUI, model and revision in the mii_softc structure. Several PHY drivers require this information also after attaching and previously had to wrap their own softc around mii_softc. NetBSD/OpenBSD also keep track of the model and revision on their mii_softc structure. All PHY drivers were updated to take advantage as appropriate. - Convert the mebers of the MII data structure to unsigned where appropriate. This is partly inspired by NetBSD/OpenBSD. - According to IEEE 802.3-2002 the bits actually have to be reversed when mapping an OUI to the MII ID registers. All PHY drivers and miidevs where changed as necessary. Actually this now again allows to largely share miidevs with NetBSD, which fixed this problem already 9 years ago. Consequently miidevs was synced as far as possible. - Add MIIF_NOMANPAUSE and mii_phy_flowstatus() calls to drivers that weren't explicitly converted to support flow control before. It's unclear whether flow control actually works with these but typically it should and their net behavior should be more correct with these changes in place than without if the MAC driver sets MIIF_DOPAUSE.

Add alc(4), a driver for Atheros AR8131/AR8132 PCIe ethernet controller. These controllers are also known as L1C(AR8131) and L2C(AR8132) respectively. These controllers resembles the first generation controller L1 but usage of different descriptor format and new register mappings over L1 register space requires a new driver. There are a couple of registers I still don't understand but the driver seems to have no critical issues for performance and stability. Currently alc(4) supports the following hardware features. o MSI o TCP Segmentation offload o Hardware VLAN tag insertion/stripping o Tx/Rx interrupt moderation o Hardware statistics counters(dev.alc.%d.stats) o Jumbo frame o WOL AR8131/AR8132 also supports Tx checksum offloading but I disabled it due to stability issues. I'm not sure this comes from broken sample boards or hardware bugs. If you know your controller works without problems you can still enable it. The controller has a silicon bug for Rx checksum offloading, so the feature was not implemented. I'd like to say big thanks to Atheros. Atheros kindly sent sample boards to me and answered several questions I had. HW donated by: Atheros Communications, Inc.

Add alc(4), a driver for Atheros AR8131/AR8132 PCIe ethernet controller. These controllers are also known as L1C(AR8131) and L2C(AR8132) respectively. These controllers resembles the first generation controller L1 but usage of different descriptor format and new register mappings over L1 register space requires a new driver. There are a couple of registers I still don't understand but the driver seems to have no critical issues for performance and stability. Currently alc(4) supports the following hardware features. o MSI o TCP Segmentation offload o Hardware VLAN tag insertion/stripping o Tx/Rx interrupt moderation o Hardware statistics counters(dev.alc.%d.stats) o Jumbo frame o WOL AR8131/AR8132 also supports Tx checksum offloading but I disabled it due to stability issues. I'm not sure this comes from broken sample boards or hardware bugs. If you know your controller works without problems you can still enable it. The controller has a silicon bug for Rx checksum offloading, so the feature was not implemented. I'd like to say big thanks to Atheros.

Disable PHY hibernation until I get more detailed hibernation programming secret. The PHY would go into sleep state when it detects no established link and it will re-establish link when the cable is plugged in. Previously it failed to re-establish link when the cable is plugged in such that it required to manually down and up the interface again to make it work. This came from incorrectly programmed hibernation parameters. According to Atheros, each PHY chip requires different configuration for hibernation and different vendor has different settings for the same chip. Disabling hibernation may consume more power but establishing link looks more important than saving power. Special thanks to Atheros for giving me instructions that disable hibernation.

Disable PHY hibernation until I get more detailed hibernation programming secret. The PHY would go into sleep state when it detects no established link and it will re-establish link when the cable is plugged in. Previously it failed to re-establish link when the cable is plugged in such that it required to manually down and up the interface again to make it work. This came from incorrectly programmed hibernation parameters. According to Atheros, each PHY chip requires different configuration for hibernation and different vendor has different settings for the same chip. Disabling hibernation may consume more power but establishing link looks more important than saving power. Special thanks to Atheros for giving me instructions that disable hibernation.

Add alc(4), a driver for Atheros AR8131/AR8132 PCIe ethernet controller. These controllers are also known as L1C(AR8131) and L2C(AR8132) respectively. These controllers resembles the first generation controller L1 but usage of different descriptor format and new register mappings over L1 register space requires a new driver. There are a couple of registers I still don't understand but the driver seems to have no critical issues for performance and stability. Currently alc(4) supports the following hardware features. o MSI o TCP Segmentation offload o Hardware VLAN tag insertion/stripping o Tx/Rx interrupt moderation o Hardware statistics counters(dev.alc.%d.stats) o Jumbo frame o WOL AR8131/AR8132 also supports Tx checksum offloading but I disabled it due to stability issues. I'm not sure this comes from broken sample boards or hardware bugs. If you know your controller works without problems you can still enable it. The controller has a silicon bug for Rx checksum offloading, so the feature was not implemented. I'd like to say big thanks to Atheros. Atheros kindly sent sample boards to me and answered several questions I had. HW donated by: Atheros Communications, Inc.

Align the PCI Express #defines with the style used for the PCI-X #defines. This also has the advantage that it makes the names more compact, iand also allows us to correct the non-uniform naming of the PCIM_LINK_* defines, making them all consistent amongst themselves. This is a mostly mechanical rename: s/PCIR_EXPRESS_/PCIER_/g s/PCIM_EXP_/PCIEM_/g s/PCIM_LINK_/PCIEM_LINK_/g When this is MFC'd, #defines will be added for the old names to assist out-of-tree drivers.

Add alc(4), a driver for Atheros AR8131/AR8132 PCIe ethernet controller. These controllers are also known as L1C(AR8131) and L2C(AR8132) respectively. These controllers resembles the first generation controller L1 but usage of different descriptor format and new register mappings over L1 register space requires a new driver.

Currently alc(4) supports the following hardware features. o MSI o TCP Segmentation offload o Hardware VLAN tag insertion/stripping o Tx/Rx interrupt moderation o Hardware statistics counters(dev.alc.%d.stats) o Jumbo frame o WOL AR8131/AR8132 also supports Tx checksum offloading but I disabled it due to stability issues. I'm not sure this comes from broken sample boards or hardware bugs. If you know your controller works without problems you can still enable it.

This change adds supports for the following controllers. o AR8151 v1.0(L1D) gigabit ethernet controller o AR8151 v2.0(L1D) gigabit ethernet controller o AR8152 v1.1(L2CB) fast ethernet controller o AR8152 v2.0(L2CB2) fast ethernet controller These controllers have the same feature of AR8131/AR8132 and support improved power saving control. The user visible change at this moment is reduced jumbo frame size from 9KB to 6KB. Many thanks to Atheros for continuing to support FreeBSD. HW donated by: Atheros Communications, Inc.

Add alc(4), a driver for Atheros AR8131/AR8132 PCIe ethernet controller. These controllers are also known as L1C(AR8131) and L2C(AR8132) respectively. These controllers resembles the first generation controller L1 but usage of different descriptor format and new register mappings over L1 register space requires a new driver. There are a couple of registers I still don't understand but the driver seems to have no critical issues for performance and stability. Currently alc(4) supports the following hardware features. o MSI o TCP Segmentation offload o Hardware VLAN tag insertion/stripping o Tx/Rx interrupt moderation o Hardware statistics counters(dev.alc.%d.stats) o Jumbo frame o WOL AR8131/AR8132 also supports Tx checksum offloading but I disabled it due to stability issues. I'm not sure this comes from broken sample boards or hardware bugs. If you know your controller works without problems you can still enable it. The controller has a silicon bug for Rx checksum offloading, so the feature was not implemented. I'd like to say big thanks to Atheros. Atheros kindly sent sample boards to me and answered several questions I had. HW donated by: Atheros Communications, Inc.

Convert the PHY drivers to honor the mii_flags passed down and convert the NIC drivers as well as the PHY drivers to take advantage of the mii_attach() introduced in r213878 to get rid of certain hacks. For the most part these were: - Artificially limiting miibus_{read,write}reg methods to certain PHY addresses; we now let mii_attach() only probe the PHY at the desired address(es) instead. - PHY drivers setting MIIF_* flags based on the NIC driver they hang off from, partly even based on grabbing and using the softc of the parent; we now pass these flags down from the NIC to the PHY drivers via mii_attach(). This got us rid of all such hacks except those of brgphy() in combination with bce(4) and bge(4), which is way beyond what can be expressed with simple flags. While at it, I took the opportunity to change the NIC drivers to pass up the error returned by mii_attach() (previously by mii_phy_probe()) and unify the error message used in this case where and as appropriate as mii_attach() actually can fail for a number of reasons, not just because of no PHY(s) being present at the expected address(es).

There are a couple of registers I still don't understand but the driver seems to have no critical issues for performance and stability. Currently alc(4) supports the following hardware features. o MSI o TCP Segmentation offload o Hardware VLAN tag insertion/stripping o Tx/Rx interrupt moderation o Hardware statistics counters(dev.alc.%d.stats) o Jumbo frame o WOL AR8131/AR8132 also supports Tx checksum offloading but I disabled it due to stability issues. I'm not sure this comes from broken sample boards or hardware bugs. If you know your controller works without problems you can still enable it. The controller has a silicon bug for Rx checksum offloading, so the feature was not implemented. I'd like to say big thanks to Atheros. Atheros kindly sent sample boards to me and answered several questions I had. HW donated by: Atheros Communications, Inc.

Add support for QAC AR816x/AR817x Gigabit/Fast Ethernet controllers. These controllers seem to have the same feature of AR813x/AR815x and improved RSS support(4 TX queues and 8 RX queues). alc(4) supports all hardware features except RSS. I didn't implement RX checksum offloading for AR816x/AR817x just because I couldn't get confirmation from the Vendor whether AR816x/AR817x corrected its predecessor's RX checksum offloading bug on fragmented packets. This change adds supports for the following controllers. o AR8161 PCIe Gigabit Ethernet controller o AR8162 PCIe Fast Ethernet controller o AR8171 PCIe Gigabit Ethernet controller o AR8172 PCIe Fast Ethernet controller o Killer E2200 Gigabit Ethernet controller Tested by: Many Relnotes: yes MFC after: 2 weeks HW donated by: Qualcomm Atheros Communications, Inc.

Add support for QAC AR816x/AR817x Gigabit/Fast Ethernet controllers. These controllers seem to have the same feature of AR813x/AR815x and improved RSS support(4 TX queues and 8 RX queues). alc(4) supports all hardware features except RSS. I didn't implement RX checksum offloading for AR816x/AR817x just because I couldn't get confirmation from the Vendor whether AR816x/AR817x corrected its predecessor's RX checksum offloading bug on fragmented packets. This change adds supports for the following controllers. o AR8161 PCIe Gigabit Ethernet controller o AR8162 PCIe Fast Ethernet controller o AR8171 PCIe Gigabit Ethernet controller o AR8172 PCIe Fast Ethernet controller o Killer E2200 Gigabit Ethernet controller Tested by: Many Relnotes: yes MFC after: 2 weeks HW donated by: Qualcomm Atheros Communications, Inc.

* AR81[3567]x allows 64bit DMA addressing of Tx/Rx buffers
Add alc(4), a driver for Atheros AR8131/AR8132 PCIe ethernet controller. These controllers are also known as L1C(AR8131) and L2C(AR8132) respectively. These controllers resembles the first generation controller L1 but usage of different descriptor format and new register mappings over L1 register space requires a new driver. There are a couple of registers I still don't understand but the driver seems to have no critical issues for performance and stability. Currently alc(4) supports the following hardware features. o MSI o TCP Segmentation offload o Hardware VLAN tag insertion/stripping o Tx/Rx interrupt moderation o Hardware statistics counters(dev.alc.%d.stats) o Jumbo frame o WOL AR8131/AR8132 also supports Tx checksum offloading but I disabled it due to stability issues. I'm not sure this comes from broken sample boards or hardware bugs. If you know your controller works without problems you can still enable it. The controller has a silicon bug for Rx checksum offloading, so the feature was not implemented. I'd like to say big thanks to Atheros. Atheros kindly sent sample boards to me and answered several questions I had. HW donated by: Atheros Communications, Inc.

Fix various NIC drivers to properly cleanup static DMA resources. In particular, don't check the value of the bus_dma map against NULL to determine if either bus_dmamem_alloc() or bus_dmamap_load() succeeded. Instead, assume that bus_dmamap_load() succeeeded (and thus that bus_dmamap_unload() should be called) if the bus address for a resource is non-zero, and assume that bus_dmamem_alloc() succeeded (and thus that bus_dmamem_free() should be called) if the virtual address for a resource is not NULL.

Add alc(4), a driver for Atheros AR8131/AR8132 PCIe ethernet controller. These controllers are also known as L1C(AR8131) and L2C(AR8132) respectively. These controllers resembles the first generation controller L1 but usage of different descriptor format and new register mappings over L1 register space requires a new driver. There are a couple of registers I still don't understand but the driver seems to have no critical issues for performance and stability. Currently alc(4) supports the following hardware features. o MSI o TCP Segmentation offload o Hardware VLAN tag insertion/stripping o Tx/Rx interrupt moderation o Hardware statistics counters(dev.alc.%d.stats) o Jumbo frame o WOL AR8131/AR8132 also supports Tx checksum offloading but I disabled it due to stability issues. I'm not sure this comes from broken sample boards or hardware bugs. If you know your controller works without problems you can still enable it. The controller has a silicon bug for Rx checksum offloading, so the feature was not implemented. I'd like to say big thanks to Atheros. Atheros kindly sent sample boards to me and answered several questions I had. HW donated by: Atheros Communications, Inc.

Make sure to not use stale ip/tcp header pointers. The ip/tcp header parser uses m_pullup(9) to get access to mbuf chain. m_pullup(9) can allocate new mbuf chain and free old one if the space left in the mbuf chain is not enough to hold requested contiguous bytes. Previously drivers can use stale ip/tcp header pointer if m_pullup(9) returned new mbuf chain. Reported by: Andrew Boyer (aboyer <> averesystems dot com) MFC after: 10 days

These controllers resembles the first generation controller L1 but usage of different descriptor format and new register mappings over L1 register space requires a new driver. There are a couple of registers I still don't understand but the driver seems to have no critical issues for performance and stability. Currently alc(4) supports the following hardware features. o MSI o TCP Segmentation offload o Hardware VLAN tag insertion/stripping o Tx/Rx interrupt moderation o Hardware statistics counters(dev.alc.%d.stats) o Jumbo frame o WOL AR8131/AR8132 also supports Tx checksum offloading but I disabled it due to stability issues. I'm not sure this comes from broken sample boards or hardware bugs. If you know your controller works without problems you can still enable it.

Add alc(4), a driver for Atheros AR8131/AR8132 PCIe ethernet controller. These controllers are also known as L1C(AR8131) and L2C(AR8132) respectively. These controllers resembles the first generation controller L1 but usage of different descriptor format and new register mappings over L1 register space requires a new driver. There are a couple of registers I still don't understand but the driver seems to have no critical issues for performance and stability. Currently alc(4) supports the following hardware features. o MSI o TCP Segmentation offload o Hardware VLAN tag insertion/stripping o Tx/Rx interrupt moderation o Hardware statistics counters(dev.alc.%d.stats) o Jumbo frame o WOL AR8131/AR8132 also supports Tx checksum offloading but I disabled it due to stability issues. I'm not sure this comes from broken sample boards or hardware bugs. If you know your controller works without problems you can still enable it.

These controllers resembles the first generation controller L1 but usage of different descriptor format and new register mappings over L1 register space requires a new driver. There are a couple of registers I still don't understand but the driver seems to have no critical issues for performance and stability. Currently alc(4) supports the following hardware features. o MSI o TCP Segmentation offload o Hardware VLAN tag insertion/stripping o Tx/Rx interrupt moderation o Hardware statistics counters(dev.alc.%d.stats) o Jumbo frame o WOL AR8131/AR8132 also supports Tx checksum offloading but I disabled it due to stability issues. I'm not sure this comes from broken sample boards or hardware bugs. If you know your controller works without problems you can still enable it. The controller has a silicon bug for Rx checksum offloading, so the feature was not implemented. I'd like to say big thanks to Atheros. Atheros kindly sent sample boards to me and answered several questions I had. HW donated by: Atheros Communications, Inc.
