Locally generated broadcast and multicast packets have pkttype set to
PACKET_LOOPBACK instead of PACKET_BROADCAST or PACKET_MULTICAST.  This
causes the pkttype match to fail to match packets of either type.

The below patch remedies this by using the daddr as a hint as to
broadcast|multicast.  While not pretty, this seems like the only way
to solve the problem short of just noting this as a limitation of the match.

This resolves bug #484
