I really tried to figure out a way to get both the Vitesse and Realtek
switches to do internal tagging but they just don't.
I'm afraid, that You have right.
The Vitesse switches can do VLAN but I just haven't implemented
it yet, but now that Adrian is using it on a Freescale board as well
I might get to it as we have some more users.
I plan to make support for VLAN filtering for this switch. Maybe we can
work together?
There are some patches to the kernel do do port separation using
only VLAN (by Vladimir Oltean) but of course I have to implement
VLAN first if I want to try to use that.
I see three possible solutions for port separation after VLAN support:
1. Use this only:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/networking/dsa/configuration.rst#n211
2. Use 8021q tag based solution.
3. Use tag_8021q tag based solution and try to use VLAN_KEEP_TAG_ENA for
dual vlan tagging.
Best Regards,
Pawel Dembicki
