Hi,

I'm not sure I understand the problem, but I have the feeling your use case
is not supported.

You can implement VLANs either with the 802.1Q [1] or the Open vSwitch [2]
drivers.

However, you can only tag one VLAN per interfaces, which as far as I know,
is the only thing that makes sense?

Cheers,
Jaime
