Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next

Jeff Kirsher says:

====================
This series contains updates to e1000e, igb and ixgbe.

Bruce Allan provide 2 minor cleanups for e1000e to resolve whitespace
issues and build warnings about unused parameters.

Carolyn provides a couple of fixes for igb, one being a fix for a
possible panic when the interface is down and receive traffic
arrives.  The second fix resolves an issue on newer parts which have
multiple checksum fields and set_ethtool was only checking to update
the first checksum of the NVM image.

Akeem provides majority of the changes in this patch set.  Akeem
provides a fix for e1000e on an issue reported from the community to
resolve the issue of unlocking swflag_mutex for 82574 and 82583
devices even if the hardware semaphore was successfully acquired.
The other patches from Akeem are against igb, where he adds support
SFP module discovery, LED blink mechanism for devices using cathodes,
LED support for i210/i211 parts and cleanup of a i2c function which
was not being used.

Matthew provides an update for igb to support a more accurate check
for a PTP RX hang.

Amir provides a patch for ixgbe to set the software prio_tc values at
initialization to the hardware setting to remove the need to reset the
device at the first time we call ixgbe_dcbnl_ieee_setets.
