kernel IPv6 multicast routing support. pim6 dense mode daemon pim6 sparse mode daemon netstat support of IPv6 multicast routing statistics Merging to the current and testing with other existing multicast routers is done by Tatsuya Jinmei <jinmei@kame.net>, who writes and maintainances the base code in KAME distribution. Make world check and kernel build check was also successful.
