Testpmd forwards packets in checksum mode that it needs to calculate
the checksum of each layer's protocol.
In process_inner_cksums, when parsing tunnel packets, inner L4 offset should be
outer_l2_len + outer_l3_len + l2_len + l3_len.
In process_outer_cksums, when parsing tunnel packets, outer L4 offset should be
outer_l2_len + outer_l3_len.
