udptunnel: Add SKB_GSO_UDP_TUNNEL during gro_complete.
When doing GRO processing for UDP tunnels, we never add SKB_GSO_UDP_TUNNEL to gso_type - only the type of the inner protocol is added (such as SKB_GSO_TCPV4). The result is that if the packet is later resegmented we will do GSO but not treat it as a tunnel. This results in UDP fragmentation of the outer header instead of (i.e.) TCP segmentation of the inner header as was originally on the wire. Signed-off-by: Jesse Gross <> Signed-off-by: David S.
