The RGMII ports on LS1043ARDB platforms require both RX and TX internal delays to be enabled. The device tree reports only the TX ID because the RX ID used to be enabled by default.
With the addition of RX ID support for the Realtek 8211F PHY driver in commit e32e4d0f58cb ("net: phy: realtek: add rx delay support for RTL8211F"), the RX ID is disabled by the driver if not reported explicitly. This causes the RX to no longer work.
Change the phy-connection-type for the RGMII ports to "rgmii-id" in order to enable both RX and TX internal delays.
