Selected device feature bits can be propagated to VLAN devices, so we can make use of TX checksum offload and TSO on VLAN-tagged packets. However, if the physical device does not do VLAN tag insertion or generic checksum offload then the test for TX checksum offload in dev_queue_xmit() will see a protocol of htons(ETH_P_8021Q) and yield false. This splits the checksum offload test into two functions: - can_checksum_protocol() tests a given protocol against a feature bitmask - dev_can_checksum() first tests the skb protocol against the device features; if that fails and the protocol is htons(ETH_P_8021Q) then it tests the encapsulated protocol against the effective device features for VLANs Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Acked-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
