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 2017-05-31

This series contains updates to ixgbe and ixgbevf only.

Scott enables support for TSO & GSO for MPLS encapsulated packets for both
ixgbe and ixgbevf.

Liwei Song fixes an issue where seqcount/seqlock in ixgbe_get_stats64()
are not initialized in time, so move the initialization into probe routine
after the transmit and receive rings are initialized.

Paul cleans up led_[on|off] for X550EM_X, since the firmware configures
the PHY & MAC and we have no PHY access so LED on/off is not supported
with this device.

Emil provides several fixes, starting with enabling RSS on VF to VF
traffic on the same PF.  Fixed PHY identification, where the previous
method was unreliable, so use a different register to ensure proper
identification.  Cleaned up the logic which could cause us to
skip the link configuration, this skipping over the link configuration
was leaving SFP+ PHY's in an unstable state, so always call
setup_mac_link().  Added RS1 (rate select 1) support for ixgbe.  Lastly,
fixed incorrect logic in the setting up of SFP+ link speed.

Mark fixes the thermal sensor event logic, where it was being executed
when there really was no thermal event.  So simplify the logic to only
execute when there is a thermal event.

Tony adds additional error checks and reporting when setting a VF MAC
address to ensure that the MAC filter was successfully added.  Also
fixed possible truncation warnings, as well as implicit fallthrough
warnings.
