====================
Intel Wired LAN Driver Updates 2015-02-05

This series contains updates to fm10k, ixgbe and ixgbevf.

Matthew fixes an issue where fm10k does not properly drop the upper-most four
bits on of the VLAN ID due to type promotion, so resolve the issue by not
masking off the bits, but by throwing an error if the VLAN ID is out-of-bounds.
Then cleans up two cases where variables were not being used, but were
being set, so just remove the unused variables.

Don cleans up sparse errors in the x550 family file for ixgbe.  Fixed up
a redundant setting of the default value for set_rxpba, which was done
twice accidentally.  Cleaned up the probe routine to remove a redundant
attempt to identify the PHY, which could lead to a panic on x550.  Added
support for VXLAN receive checksum offload in x550 hardware.  Added the
Ethertype Anti-spoofing feature for affected devices.

Emil enables ixgbe and ixgbevf to allow multiple queues in SRIOV mode.
Adds RSS support for x550 per VF.  Fixed up a couple of issues introduced
in commit 2b509c0cd2 ("ixgbe: cleanup ixgbe_ndo_set_vf_vlan"), fixed
setting of the VLAN inside ixgbe_enable_port_vlan() and disable the
"hide VLAN" bit in PFQDE when port VLAN is disabled.  Cleaned up the
setting of vlan_features by enabling all features at once.  Fixed the
ordering of the shutdown patch so that we attempt to shutdown the rings
more gracefully.  We shutdown the main Rx filter in the case of Rx and we
set the carrier_off state in the case of Tx so that packets stop being
delivered from outside the driver.  Then we shutdown interrupts and NAPI,
then finally stop the rings from performing DMA and clean them.  Added
code to allow for Tx hang checking to provide more robust debug info in
the event of a transmit unit hang in ixgbevf.  Cleaned up ixgbevf logic
dealing with link up/down by breaking down the link detection and up/down
events into separate functions, similar to how these events are handled
in other drivers.  Combined the ixgbevf reset and watchdog tasks into a
single task so that we can avoid multiple schedules of the reset task when
we have a reset event needed due to either the mailbox going down or
transmit packets being present on a link down.

v2: Fixed up patch #03 of the series to remove the variable type change
    based on feedback from David Laight

This allows one to create VXLAN virtual interfaces that provide
Layer 2 Networks over Layer 3 Networks. VXLAN is often used
to tunnel virtual network infrastructure in virtualized environments.
