AFACT this issue is not AR803x specific. I was hit by the same problem with QCA833x switch on imx6dl-yapp4. Though, we are currently the only platform in tree using this chip and Shawn already has the fix in his tree. I am not aware of any other PHY drivers that my cause problems. $ git log --oneline v5.0..v5.1-rc1 --grep=RGMII --author=Vinod -- drivers/net/ 6d4cd041f0af net: phy: at803x: disable delay only for RGMII mode a968b5e9d587 net: dsa: qca8k: Enable delay for RGMII_ID mode 5ecdd77c61c8 net: dsa: qca8k: disable delay for RGMII mode cd28d1d6e52e net: phy: at803x: Disable phy delay for RGMII mode Michal
