[vbox-dev] Control IP multicast reception via API?

Do the host-only network interfaces in any way behave differently to the typical tun/tap Ethernet devices Linux offers? I mean in terms of multicast reception. So if I bridge from the physical device to the host-only interface then it should be able to process multicast pakets as well right?

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 :)
