to be more rfc2292 complient, move ip6.h and icmp6.h into netinet. (netinet6/{ip6,icmp6}.h is non-standard path - these files should go away) it was not possible to use cvsmove in this case. when you try to look at history, chase it toward netinet6/{ip6,icmp6}.h.

to be more rfc2292 complient, move ip6.h and icmp6.h into netinet. (netinet6/{ip6,icmp6}.h is non-standard path - these files should go away) it was not possible to use cvsmove in this case. when you try to look at history, chase it toward netinet6/{ip6,icmp6}.h.
