Previously we falsely relied on the PHY driver to unconditionally enable the internal RX delay. Since the following fix for the PHY driver this is not the case anymore: commit 7b005a1742be ("net: phy: mscc: configure both RX and TX internal delays for RGMII") In order to enable the delay we need to set the connection type to "rgmii-rxid". Without the RX delay the ethernet is not functional at all.
