Yoshinobu Inoue 0fea3d5165 IPv6 multicast routing.
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.
