  Modified files:
    etc                  rc.network6 
  Added files:
    etc                  pim6dd.conf pim6sd.conf 
  Log:
  Prevent multicast packets from being sent over stf0 interface,
  to avoid error messages printed on /var/log/messages.
  
    Recently added "stf" interface has IFF_MULTICAST bit set,
    because IPv6 don't work on non IFF_MULTICAST set interfaces
    in current implementation.
    But "stf" interface is multi-dest IPv6 over IPv4 tunnel, so
    can't treat multicast packet with no special configuration.
  
    On the other hand, tools like "rtadvd", "pim6dd", "pim6sd"
    send messages on IFF_MULTICAST set interfaces by default.
    So there will be many bogus error message on /var/log/messages,
    that multicast packets sent to "stf0" failed.
  
    So,
  
     -strip "stf0" from rtadvd sending interfaces in rc.network6
      ("rtadvd" is a daemon used only for local subnet, so it
       will never need to send its packets over "stf0" interfaces.)
  
     -Add default configuration files for "pim6dd" and "pim6sd",
      and disable "stf0" in those files.
