From e585f23636370320bc2071ca5ba2744ae37c3e51 Mon Sep 17 00:00:00 2001 From: Tom Herbert Date: Tue, 4 Nov 2014 09:06:54 -0800 Subject: 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 Signed-off-by: David S.
