====================
Fixes for tunnel checksum and segmentation offloads

This patch series is a subset of patches I had submitted for net-next.  I
plan to drop these two patches from the v3 of "Fix Tunnel features and
enable GSO partial for several drivers" and I am instead submitting them
for net since these are truly fixes and likely will need to be backported
to stable branches.

This series addresses 2 specific issues.  The first is that we could
request TSO on a v4 inner header while not supporting checksum offload of
the outer IPv6 header.  The second is that we could request an IPv6 inner
checksum offload without validating that we could actually support an inner
IPv6 checksum offload.
