Jeff Kirsher says:

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

This series contains updates to ixgbe and ixgbevf.

Pavel Tikhomirov fixes a typo where we were incrementing transmit stats
instead of receive stats on the receive side.

Emil updates the ixgbevf driver to use bit operations for setting and
checking the adapter state.

Chas Williams adds the new NDO trust feature check so that the VF guest
has the ability to set the unicast address of the interface, if it is a
trusted VF.

Alex cleans up the driver to that the only time we add a PF entry to the
VLVF is either for VLAN 0 or if the PF has requested a VLAN that a VF
is already using.  Also adds support for generic transmit checksums,
giving the added advantage is that we can support inner checksum offloads
for tunnels and MPLS while still being able to transparently insert
VLAN tags.  Lastly, changed ixgbe so that we can use the ethtool
rx-vlan-filter flag to toggle receive VLAN filtering on and off.

Mark cleans up the ixgbe driver by making all op structures that do not
change constants.  Also fixed flow control for Xeon D KR backplanes, since
we cannot use auto-negotiation to determine the mode, we have to use
whatever the user configured.

Sowmini Varadhan updates ixgbe to use eth_platform_get_mac_address()
instead of the arch specific solution that was added by a previous
commit.

Don fixed an issue where it was possible that a system reset could occur
when we were holding the SWFW semaphore lock, which the next time the
driver loaded would see it incorrectly as locked.

v2: updated patch 8 of the series to include a minor flags issue where
    we had lost NETIF_F_HW_TC and we were setting NETIF_F_SCTP_CRC in
    two different areas, when we only needed/wanted it in one spot.
