For the vifs on dom0 side, right?

They shouldn't receive every packet because the bridge should automatically 
forward packets to the right vif, in the common case.  I imagine setting them 
promiscuous is part and parcel of avoiding them having a MAC address: the MAC 
the bridge sees is that of the guest.

This is an educated guess, since I generally stay clear of the networking 
config!
