    esp: Add a software GRO codepath · 7785bba2

    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.
