2022-11-29selftests/net: add csum offload testWillem de Bruijn
Test NIC hardware checksum offload: - Rx + Tx - IPv4 + IPv6 - TCP + UDP Optional features: - zero checksum 0xFFFF - checksum disable 0x0000 - transport encap headers - randomization See file header for detailed comments. Expected results differ depending on NIC features: - CHECKSUM_UNNECESSARY vs CHECKSUM_COMPLETE - NETIF_F_HW_CSUM (csum_start/csum_off) vs NETIF_F_IP(V6)_CSUM Signed-off-by: Willem de Bruijn <willemb@google.com> Link: https://lore.kernel.org/r/20221128140210.553391-1-willemdebruijn.kernel@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
