  MFC 193880,193887:
  r193880:
    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.
