Hi Rafa??

Take a step back. Don't assume VLANs is the only way to do this. Look
at what Florian is doing with Starfighter and Gunter is doing with
Marvell chips. Recent patches allow the hardware to do the switching
between ports with these devices. See if you can use a similar scheme
with your chip.

What we don't want is X chip families and Y different ways to
configure the features. Ideal we want X chip families, and one way to
configure them all.
