Merge branch '10GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue

Jeff Kirsher says:

====================
10GbE Intel Wired LAN Driver Updates 2016-05-04

This series contains updates to ixgbe, ixgbevf and traffic class helpers.

Sridhar adds helper functions to the tc_mirred header to access tcf_mirred
information and then implements them for ixgbe to enable redirection to
a SRIOV VF or an offloaded MACVLAN device queue via tc 'mirred' action.

Amritha adds support to set filters with multiple header fields (L3,L4)
to match on.

KY Srinivasan from Microsoft add Hyper-V support into ixgbevf.

Emil adds 82599 sub-device IDs that were missing from the list of parts
that support WoL.  Then simplified the logic we use to determine WoL
support by reading the EEPROM bits for MACs X540 and newer.

Preethi cleaned up duplicate and unused device IDs.  Fixed our ethtool
stat reporting where we were ignoring higher 32 bits of stats registers,
so fill out 64 bit stat values into two 32 bit words.

Babu Moger from Oracle improves VF performance issues on SPARC.

Alex Duyck cleans up some of the Hyper-V implementation from KY so that
we can just use function pointers instead of having to identify if a
given VF is running on a Linux or Windows PF.

Usha makes sure that DCB and FCoE is disabled for X550EM_x/a MACs and
cleans up the DCB initialization in the process.

Tony cleans up the API for ixgbevf_update_xcast_mode() so we do not
have to pass in the netdev parameter, since it was never used in the
function.
