Subject: No GSOs to i40e with VXLAN

Hi all,

I quickly tested VXLAN on i40e with net-next with commit id 
f9da455b93f6ba076935b4ef4589f61e529ae046 and the i40e driver has stopped 
receiving GSOs even when advertising tx-udp_tnl-segmentation which means 
our VXLAN segmentation offload. I am guessing this has something to do
with Tom's recent UDP work but this is just a guess as unfortunatly I
do not have the time to debug this, but I am signing up to review and test 
patches fixing this issue.

The driver still gets GSOs with non VXLAN traffic (tested with TCP).

Thanks

Joseph
