This actually indicates something is wrong. When passed PHY_INTERFACE_MODE_RGMII, the PHY driver should change the PHY to not add delays, overriding the strapping. Given my previous comment, you need to spend some time understanding what is going on here. Something is not correct. https://elixir.bootlin.com/linux/v6.15/source/Documentation/devicetree/bindings/net/ethernet-controller.yaml#L287 Andrew
