I was hoping this would fix the missing vlan tag for traffic that goes
through the switch.
I just tested https://github.com/openwrt/openwrt/pull/10643 rebased on
current master
and the issue is the same: tagged vlan to tagged vlan forwarded by the
switch is sent untagged while tagged traffic that goes
to/from the CPU works as expected. It does not seem to be related to
the received tag. It looks like the tag
is added correctly by the CPU but the switch is not configured
correctly to add a tag for traffic to a specific vlan.
I would bet it is the internal switch vlan setup, not the linux side.
BTW, it might be time to merge that PR as, AFAIK, this vlan issue
affects the SoC, not that specific device.

Luiz
