This results from current (before my cpu-port patches) implementation in driver where cpu-port is fixed to port 6. On Mt7530 port 6 supports rgmii and trgmii. On mt7531 port6 only supports sgmii (which is basicly 2500base-x). Afaik it does not support 1G. Port 5 on mt7531 supports rgmii or sgmii (dual sgmii mode) but seems not reflected yet in txt. On thing more to change when converting txt to yaml. regards Frank
