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.
