udp: pass udp_offload struct to UDP gro callbacks
This patch introduces udp_offload_callbacks which has the same GRO functions (but not a GSO function) as offload_callbacks, except there is an argument to a udp_offload struct passed to gro_receive and gro_complete functions. This additional argument can be used to retrieve the per port structure of the encapsulation for use in gro processing (mostly by doing container_of on the structure).
