This patch has not urgent for this release, postponing it to next release.

This way the structure is very hard to read.
May I ask to indent field comments as it is done in
other rte_net structures (e.g. rte_ipv4_hdr, rte_udp_hdr,
rte_geneve_hdr). Personally I don't care if it will be
indent by TABs or spaces, however, it looks like TABs are
used in more places.

Also there are spelling bugs [1].
