Hi,

> To Frank:

I ack krzysztof, that the change is really huge and it is hard to understand what exactly is changed and why. So please split. I have converted
it to yaml, but not have changed the logic itself. I guess you know the switch better than me.

i only know that port 5 and 6 are possible, not about the other ports. Afair there was a check if port 5 or 6 (followed by available modes
like rgmii, trgmii or sgmii) and then allow cpu-port-mode else allow only user-port mode. Had not changed this, so currently only these 2
ports can be used as CPU.

my patches (and the version from Vladimir that was merged) only solves the Problem that CPU-Port was fixed to 6 before. I tested Patches on r2
(mt7530) and r64 too (mt7531) that they do not break anything. But i have not disabled port 6 (maybe i had to do so for a port5-only mode), only
enabled port 5 too and run iperf3 over a vlan-aware bridge between wan-port and port 5.
