udp: Changes to udp_offload to support remote checksum offload
Add a new GSO type, SKB_GSO_TUNNEL_REMCSUM, which indicates remote checksum offload being done (in this case inner checksum must not be offloaded to the NIC). Added logic in __skb_udp_tunnel_segment to handle remote checksum offload case. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
