I notice this board still has messed up rgmii delays, using phy-mode =
"rgmii", not "rgmii-id". How does com,rx-prog-swap interact with rgmii
delays? Is the sample point logic before or after the rgmii delay
logic in the MAC clock pipeline?

I think i also questioned max-speed = <1000>. Has this
arch/arm64/boot/dts/qcom/qcs615-ride.dts been merged?
