DSA doesn't allow me to use switch (hardware) VLANs. I would need to
handle all forwarding in CPU. The most powerful Broadcom MIPS SoC -
BCM4706 - can handle about 130 Mb/s. Less powerful - BCM4718A1 - only
about 50 Mb/s.
This is way too bad for performance when there is a 1 Gb/s switch and
too bad for CPU usage.

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.

Now I know about Broadcom tag, I'm aware it's not the only way and you
can be sure I'm looking for the one, most common way of handling this.

What do you mean by these recent patches? Has DSA recently received a
support for bridging ports in the hardware? Like setting VLANs using
some "bridge" comment (nl API) or something? Because I'm not aware of
that.
