With IGMP version 1 and 2 it is possible to inject a unicast report to a client
which will make it ignore multicast reports sent later by the router.
The fix is to only accept the report if is was sent to a multicast or unicast
address. Fix from David Stevens at IBM and will be made upstream shortly.
