Merge branch '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue

====================
40GbE Intel Wired LAN Driver Updates 2017-10-17
This series contains updates to i40e and ethtool.
Alan provides most of the changes in this series which are mainly fixes
and cleanups. Renamed the ethtool "cmd" variable to "ks", since the new
ethtool API passes us ksettings structs instead of command structs.
Cleaned up an ifdef that was not accomplishing anything. Added function
header comments to provide better documentation. Fixed two issues in
i40e_get_link_ksettings(), by calling
ethtool_link_ksettings_zero_link_mode() to ensure the advertising and
link masks are cleared before we start setting bits. Cleaned up and fixed
code comments which were incorrect. Separated the setting of autoneg in
i40e_phy_types_to_ethtool() into its own conditional to clarify what PHYs
support and advertise autoneg, and makes it easier to add new PHY types in
the future. Added ethtool functionality to intersect two link masks
together to find the common ground between them. Overhauled i40e to
ensure that the new ethtool API macros are being used, instead of the
old ones. Fixed the usage of unsigned 64-bit division which is not
supported on all architectures.
Sudheer adds support for 25G Active Optical Cables (AOC) and Active Copper
Cables (ACC) PHY types.
