40GbE Intel Wired LAN Driver Updates 2016-04-27

This series contains updates to i40e and i40evf.

Alex Duyck cleans up the feature flags since they are becoming pretty
"massive", the primary change being that we now build our features list
around hw_encap_features.  Added support for IPIP and SIT offloads,
which should improvement in throughput for IPIP and SIT tunnels with
the offload enabled.

Mitch adds support for configuring RSS on behalf of the VFs, which removes
the burden of dealing with different hardware interfaces from the VF
drivers and improves future compatibility.  Fix to ensure that we do not
panic by checking that the vsi_res pointer is valid before dereferencing
it, after which we can drink beer and eat peanuts.

Shannon does come housekeeping in i40e_add_fdir_ethtool() in preparation
for more cloud filter work.  Added flexibility to the nvmupdate
facility by adding the ability to specify an AQ event opcode to wait on
after Exec_AQ request.

Michal adds device capability which defines if an update is available and
if a security check is needed during the update process.

Kamil just adds a device id to support X722 QSFP+ device.

Greg fixes an issue where a mirror rule ID may be zero, so do not return
invalid parameter when the user passes in a zero for a rule ID.  Adds
support to steer packets to VSIs by VLAN tag alone while being in
promiscuous mode for multicast and unicast MAC addresses.

Jesse fixes the driver from offloading the VLAN tag into the skb any
time there was a VLAN tag and the hardware stripping was enabled, to
making sure it is enabled before put_tag.

v2: Dropped patch 8 ("i40e: Allow user to change input set mask for flow
    director") while Kiran reworks a more generalized solution based
    on feedback from David Miller.
