Thinking a bit more about this I could envision some changes to the
vlan code too. I image one could create one vlan interface which will listen
to several VLANs. One VLAN is the primary VLAN and is used in the tx path
by default. The bridge would be able to filter on individual VLANs received
from such interface and be able to chose outgoing VLAN too.
