The correct setting for the RGMII ports on LS1046ARDB is to enable delay on both Rx and Tx so the interface mode used must be PHY_INTERFACE_MODE_RGMII_ID. 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 RGMII_TXID. The LS1046ARDB uses two such PHYs in RGMII_ID mode but in the device tree the mode was described as "rgmii". Changing the phy-connection-type to "rgmii-id" to address the issue.
