[IGMP]: workaround for IGMP v1/v2 bug
From: David Stevens <dlstevens@us.ibm.com>
As explained at:
http://www.cs.ucsb.edu/~krishna/igmp_dos/
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.
