Downstream OpenWrt uses the same format as documented in
Documentation/devicetree/bindings/net/dsa/lantiq-gswip.txt
A fixed-link is not present, meaning that it's good to opt out for now.

I added a TODO so we can fix the .dts downstream in OpenWrt.
Upstreaming the .dts files from downstream is also on this ever growing list...


Best regards,
Martin
