For netinet6 you will find the "helper" functions which are still
unused. ip6_input() will need the same check that ip_input() has
if we want feature parity with legacy IP (being able to not filter on
the "inner" header/payload from an IPsec tunnel mode)

I am unsure why it's not yet there. Anyone know a reason other than
"just missing"?
