Hi, retested series on bananpi r2 on 6.3-rc6 (after throughput is fixed for mt7623/trgmii too) with additional patches: "net: dsa: implement preferred cpu port handling" by Vladimir Oltean to stay on gmac0 by default "net: dsa: mt7530: add support for changing DSA master" by Richard van Schagen looks good so far, but i have not managed how to change dsa master from the preferred port (eth0) to the second one... any idea how the correct syntax is for iproute2? at least vladimirs patch should be included when applying this series regards Frank
