====================
Intel Wired LAN Driver Updates 2014-09-06

This series contains updates to e1000 and igb.

Krzysztof provides a patch to cleanup the coding style in e1000 to quiet
checkpatch.pl warnings.

Todd adds two boolean flags to igb to allow for changes in the
advertised EEE speeds from ethtool.
