gre_offload: statically build GRE offloading support
GRO/GSO layers can be enabled on a node, even if said node is only forwarding packets. This patch permits GSO (and upcoming GRO) support for GRE encapsulated packets, even if the host has no GRE tunnel setup. Signed-off-by: Eric Dumazet <> Cc: H.K. Jerry Chu <> Signed-off-by: David S. Miller <>
