source address selection.
support 486 which lacks pentium_mhz from Jim Rees <email@example.com>
in default KAME(support MIP6 kernel only)
Otherwise it will work in IGMPv2-compatible mode if some other hosts send an IGMPv2 join to IPv4 linklocal multicast group 184.108.40.206/24. Since not a few IPv4 implementation joins in 220.127.116.11, IGMPv3 is not used actually without this fix.
reduce redirect message when ipsec and mip6 tunnel
(otherwise, you cannot build icmp6.c and ip6_input.c other than NetBSD. I'm not sure this is the right way, though...)
with vulnerable openssl.
packets, IGMPv3 (S,G) join is just regarded as (*,G). (It's a ToDo task)
