This patch extends the xfrm_type by an encap function pointer and implements esp4_gso_encap and esp6_gso_encap. These functions doing the basic esp encapsulation for a GSO packet. In case the GSO packet needs to be segmented in software, we add gso_segment functions. This codepath is going to be used on esp hardware offloads.

We need a fallback for ESP at layer 2, so split esp_output into generic functions that can be used at layer 3 and layer 2 and use them in esp_output. We also add esp_xmit which is used for the layer 2 fallback. Signed-off-by: NSteffen Klassert <steffen.klassert@secunet.com>

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: NSteffen Klassert <steffen.klassert@secunet.com>
