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 2017-04-05

This series contains updates to fm10k only.

Phil Turnbull from Oracle fixes an issue where the argument provided to
FM10K_REMOVED macro was not what was expecting.

Jake modifies the driver to replace the bitwise operators and defines with
a BITMAP and enumeration values to avoid race conditions.  Also future
proof the driver so that developers do not have to remember to re-size the
bitmaps when adding new values.  Fixed the wording of a code comment to
avoid stating that we return a value for a void function.

Ngai-Mint makes sure that when configuring the receive ring, we make sure
the receive queue is disabled.  Fixed an issue where interfaces were
resetting because the transmit mailbox FIFO was becoming full since the
host was not ready, so ensure the host is ready before queueing up
mailbox messages.
