[net-next 0/2][pull request] Intel Wired LAN Driver Updates 2014-09-06

[net-next 0/2][pull request] Intel Wired LAN Driver Updates 2014-09-06

[Jeff Kirsher]

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.

The following are changes since commit cfecec56ae7c7c40f23fbdac04acee027ca3bd66:
  mlx4: only pull headers into skb head
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next master

Krzysztof Majzerowicz-Jaszcz (1):
  e1000: e1000_ethertool.c coding style fixes

Todd Fujinaka (1):
  igb: add flags to set eee advertisement mode

[net-next 1/2] e1000: e1000_ethertool.c coding style fixes

[Jeff Kirsher]

From: Krzysztof Majzerowicz-Jaszcz <cristos@vipserv.org>

Fixed many errors/warnings and checks in e1000_ethtool.c reported
by checkpatch.pl.  Suggestions from Joe Perches and Alexander Duyck
applied as well

[net-next 2/2] igb: add flags to set eee advertisement mode

[Jeff Kirsher]

From: Todd Fujinaka <todd.fujinaka@intel.com>

Change e1000_set_eee and e1000_set_eee_i35(0|4) to allow
changes in the advertised EEE speeds from ethtool. Adds two boolean
flags to e1000_set_eee_i35(0|4) to pass in advertised speed data.
