> Currently, IAVF's decode_rx_desc_ptype() correctly reports payload type of
> L4 for IPv4 UDP packets and IPv{4,6} TCP, but only L3 for IPv6 UDP.
> Originally, i40e, ice and iavf were affected.
> Commit 73df8c9e3e3d ("i40e: Correct UDP packet header for non_tunnel-
> ipv6") fixed that in i40e, then commit 638a0c8c8861 ("ice: fix incorrect
> payload indicator on PTYPE") fixed that for ice.
> IPv6 UDP is L4 obviously. Fix it and make iavf report correct L4 hash type for
> such packets, so that the stack won't calculate it on CPU when needs it.
