From de58647b4301fe181f9c38e8b46f7021584ae427 Mon Sep 17 00:00:00 2001 From: Alexander Lobakin Date: Wed, 1 Mar 2023 12:59:08 +0100 Subject: iavf: fix non-tunneled IPv6 UDP packet type and hashing 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.
