Doing research on another problem, I noticed that this would
break user mode spanning tree (RSTP) code.

The daemon assumes that bridge is promicious mode and therefore
will receive all link-level multicast packets.


Just took another look at RSTP code and I see that's its using
a packet socket with filter to catch STP frames.

Would setting IFF_ALL_MULTI solve the problem?  STP packets
are all multicast.

Thanks
