When GRE support was added in linux-3.14, CHECKSUM_COMPLETE handling broke on GRE+IPv6 because we did not update/use the appropriate csum : GRO layer is supposed to use/update NAPI_GRO_CB(skb)->csum instead of skb->csum Tested using a GRE tunnel and IPv6 traffic. GRO aggregation now happens at the first level (ethernet device) instead of being done in gre tunnel. Native IPv6+TCP is still properly aggregated.
