Can you tcpdump this?

This may be related to an llentry related regression which Xin Li 
recently posted a patch for, it appears that layer 2 addresses for 
multicast/broadcast datagrams may be broken in 8.0-BETA2.

Although I haven't tested this myself since committing the SSM code 
around April, where I observed such traffic was correct.
