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 Relnotes: yes

Fix a long standing bug in MAC statistics register access. One additional register was erroneously added in the MAC register set such that 7 TX statistics counters were wrong.

MFC r263957:

2014-04-14T04:51:59Z

Increase the number of TX DMA segments from 32 to 35. It turned out 32 is not enough to support a full sized TSO packet. While I'm here fix a long standing bug introduced in r169632 in bce(4) where it didn't include L2 header length of TSO packet in the maximum DMA segment size calculation.

Switch some PCI register reads from using magic numbers to using the names

Align the PCI Express #defines with the style used for the PCI-X

2012-09-18T22:04:59Z

#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.

Close a race where SIOCGIFMEDIA ioctl get inconsistent link status.

Because driver is accessing a common MII structure in mii_pollstat(), updating user supplied structure should be done before dropping a driver lock. Reported by: Karim (fodillemlinkarimi <> gmail dot com)

Disable PHY hibernation until I get more detailed hibernation

2011-08-22T20:33:05Z

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.
