Thanks!
I guessed from the name and other uses that __constant_htons() is just
a version of htons() optimized for values that are constant at compile
time. Is this right? But htons() is fine too in any case.

If you look at the original files, the whole ip_vs_proto_ah.c and
ip_vs_proto_esp.c are 100% identical except for the protocol names /
constants :-/ So I stuck with this pattern for now. Maybe it would
make sense to join those two files in a change separate from the v6
functionality? There's already a lot of duplication in the existing
IPVS that could be removed...
