I noticed a `nasty' dependency between the structs ip6protosw and protosw:
pffindproto() is used by both ipv6 & ipv4, on separate tables of different
structures.  If only one of the two changes, pffindproto() will fail for
IPv6.  Is fixing this onion peeling problem something that can be squeezed
in prior to 1.5 ?
