Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue

Jeff Kirsher says:

====================
100GbE Intel Wired LAN Driver Updates 2015-12-22

This series contains updates to fm10k only.

Bruce cleans up the initialization of fm10k_workqueue at the global level,
which fixes a checkpatch.pl error.  Made several other cleanups of the
driver, like making structures that do not change constant, remove unused
code, cleanup code comments and use boolean states true/false instead of
an integer since a bool is all that is needed.

Jacob fixed the TLV format for little endian structures which are 4 byte
aligned copy, so add an additional __aligned(4) and __packed to ensure
that these structures are actually 4 byte aligned and packed correctly.
Updated the driver to use ether_addr_equal() instead of memcmp() to
compare MAC addresses.

Alex Duyck cleans up the exception handling so all of the paths result in
a similar state if we fail.  Specifically the driver will now unload the
mailbox interrupt, free the queue vectors and MSI-X, and then detach the
interface.
