There are many many changes since last KAME merge. TODO: - The definitions of SADB_* in sys/net/pfkeyv2.h are still different from RFC2407/IANA assignment because of binary compatibility issue. It should be fixed under 5-CURRENT. - ip6po_m member of struct ip6_pktopts is no longer used. But, it is still there because of binary compatibility issue. It should be removed under 5-CURRENT.
