There's nothing in the API controlling this, and the reason is that the 
emulation itself deals with ethernet frames. It couldn't care less what 
they mean. Of course the actual behavior heavily depends on the 
networking mode (NAT definitely doesn't handle multicast in a sensible 
way), and bridged/host only/internal network should be able to handle 
them. Theoretically. Not aware of this getting tested :)
