    Well there is I think nothing unusual in this net scheme. And by for example
    the increasing setups with kvm/bridging it will be needed more and more.

    Yes - that is the clear way. But there's not really straihtforward way to do
    this. The clear approach would be to extend struct net_device for list of these
    mac addresses and let the drivers (binding) fill it and bridge to process it.
    But I don't know.
