Ok, so for the libvirt API we should define that the lookup-by-mac API
will not return VLAN devices, since we cant provide a 1-1 lookup there
Why would you do that ? When the user asks for interfaces with a MAC,
you don't know if they are looking for a VLAN or base device. If they
want the VLAN, how would they look that up ?
