====================
Intel Wired LAN Driver Updates 2014-10-23

This series contains updates to i40e and i40evf.

Jesse modifies the i40e driver to only notify the firmware on link up/down
and qualified module events.  Also simplified the job of managing link
state by using the admin queue receive event for link events as a signal
to tell the driver to update link state.

Jeff (me) cleans up the inconsistent use of tabs for indentation in the admin
queue command header file.

Neerav converts the use of udelay() to usleep_range().

Anjali fixes a bug where receive would stop after some stress by adding
a sleep and restart as well as moving the setting of flow control because
it should be done at a PF level and not a VSI level.

Mitch adds code to handle link events when updating the PF switch, which
allows link information to be properly provided to VFS in all cases.

Catherine adds driver support for 10GBaseT and bumps driver version.
