esp: Add a software GRO codepath
This patch adds GRO ifrastructure and callbacks for ESP on ipv4 and ipv6. In case the GRO layer detects an ESP packet, the esp{4,6}_gro_receive() function does a xfrm state lookup and calls the xfrm input layer if it finds a matching state. The packet will be decapsulated and reinjected it into layer 2. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
