The __constant_htons() is unnecessary, the simple macro htons()
is smart enough to figure out what is constant. The current style
preference is to use htons() instead; shorter is better.

It seems this patch makes two different changes, but changelog is vague.
(As if we were not dissecting flows in IPv4/IPv6 packets ...)
How about :
1) Fix a problem if IPIP is tunneled into IPv6
Prior code assumed IPIP was encapsulated into IPv4 only.
2) Add support for IPPROTO_IPV6
Thanks
BTW it looks like we do not support ETH_P_8021AD yet
