  # IPv6 snooping bug - OSPFv3 hellos jump off the bridge
    * Look at output of `netstat -s | grep invalid` to see "invalid headers"
  # Problem with IPv6 addressing in namespaces (CORE SVN snapshot has workaround):
    * 2.6.34 and 2.6.35 seem to have problems ([http://www.spinics.net/lists/netdev/msg137122.html possibly related problem]) as reported by users [http://pf.itd.nrl.navy.mil/pipermail/core-users/2010-September/000269.html here].
