>Instead of passing 3 separate pointers back and forth to get packet template
>(dummy) params, directly return a structure containing them. Then, use a
>macro to compose compound literals and avoid code duplication on return
>path.
>Now, dummy packet type/name is needed only once to return a full correct
>triple pkt-pkt_len-offsets, and those are all one-liners.
>dummy_ipv4_gtpu_ipv4_packet_offsets is just moved around and renamed
>(as well as dummy_ipv6_gtp_packet_offsets) with no function changes.
