====================
Intel Wired LAN Driver Updates

This series contains updates to igb and i40e.

Todd provides a fix for 82580 devices in igb, where the ethtool
loopback test was missing 82580 copper devices.

Jesse provides five fixes/cleanups to i40e based on feedback from
Joe Perches and the community.

v2: fixed up patch 5 in the series based on feedback from Joe Perches
    and David Miller
