Hi Birger,
This looks good. I will try to have a closer look in the next days.

Hi Hauke,
it looks as if there could be a more elegant solution to this, tomn just

this on the forum:
https://forum.openwrt.org/t/support-for-rtl838x-based-managed-switches/57875
I did not have time to test it so far, though.

The RTL8380-RTL9300 switches only forward packets when VLAN ID 1 is
configured. Do not use the standard failsafe configuration for DSA
accessing the default port directly, but configure a switch on the lan1
interface instead.
This will add the VLAN ID 1 configuration to the switch:
$ bridge vlan show
port vlan-id
lan1 1 PVID Egress Untagged
switch 1 PVID Egress Untagged
