40GbE Intel Wired LAN Driver Updates 2016-02-18

This series contains updates to i40e and i40evf only.

Alex Duyck provides all the patches in the series to update and fix the
drivers.  Fixed the driver to drop the outer checksum offload on UDP
tunnels, since the issue is that the upper levels of the stack never
requested such an offload and it results in possible errors.  Updates the
TSO function to just use u64 values, so we do not have to end up casting
u32 values.  In the TSO path, factored out the L4 header offsets allowing
us to ignore the L4 header offsets when dealing with the L3 checksum and
length update.  Consolidates all of the spots where we were updating
either the TCP or IP checksums in the TSO and checksum path into the TSO
function.  Fixed two issues by adding support for IPv4 encapsulated in
IPv6, first issue was the fact that iphdr(skb)->protocol was being used to
test for the outer transport protocol which breaks IPv6 support.  The second
was that we cleared the flag for v4 going to v6, but we did not take care
of txflags going the other way.  Added support for IPv6 extension headers
in setting up the Tx checksum.  Added exception handling to the Tx
checksum path so that we can handle cases of TSO where the frame is bad,
or Tx checksum where we did not recognize a protocol.  Fixed a number of
issues to make certain that we are using the correct protocols when
parsing both the inner and outer headers of a frame that is mixed between
IPv4 and IPv6 for inner and outer.  Updated the feature flags to reflect
the newly enabled/added features.

Sorry, no witty patch descriptions this time around, probably should
let Mitch help in writing patch descriptions for Alex. :-)
