The patch set ensures all RGMII modes are treated correctly by the FMan driver and sets the phy-connection-type to "rgmii-id" to restore functionality. Previously Rx internal delay was set by board pull-ups and was left untouched by the PHY driver. Since commit 1b3047b5208a80 ("net: phy: realtek: add support for configuring the RX delay on RTL8211F") the Realtek 8211F PHY driver has control over the RGMII RX delay and it is disabling it for other modes than RGMII_RXID and RGMII_ID. Please note that u-boot in particular performs a fix-up of the PHY connection type and will overwrite the values from the Linux device tree. Another patch set was sent for u-boot and one needs to apply that [1] to the boot loader, to ensure this fix is complete, unless a different bootloader is used.
