====================
Intel Wired LAN Driver Updates 2014-07-01

This series contains updates to i40e, i40evf, igb and ixgbe.

Shannon adds the Base Address High and Low to the admin queue structure
to simplify the logic in the configuration routines.  Also adds code to
clear all queues and interrupts to help clean up after a PXE or other
early boot activity.

Kevin fixes mask assignment value since -1 cannot be used for unsigned
integer types.

Mitch fixes an issue where in some circumstances the reply from the PF
would come back before we were able to properly modify the admin queue
pending and required flags.  This would mess up the flags and put the
driver in an indeterminate state, so fix this by simply setting the flags
before sending the request to the admin queue.  Also changes the branding
string for i40evf to reduce confusion and to match up with our other
marketing materials.

Kamil adds a new variable defining admin send queue (ASQ) command write
back timeout to allow for dynamic modification of this timeout.

Anjali fix a bug in the flow director filter replay logic, so that we
call a replay after a sideband reset correctly.

Jesse adds code to initialize all members of the context descriptor to
prevent possible stale data.

Christopher fixes i40e to prevent writing to reserved bits, since the
queue index is only 0-127.

Jacob removes the unneeded header export.h from the i40e PTP code.
Fixes ixgbe PTP code where the PPS signal was not correct, as it
generates a one half HZ clock signal, it only generates one level
change per second.  To generate a full clock, we need two level changes
per second.

Todd provides a fix for igb to bring up link when the PHY has powered
up, which was reported by Jeff Westfahl.
