The old logic always enabled the TX-delay when the phy-mode was set to PHY_INTERFACE_MODE_RGMII. There are dedicated phy-modes which tell the PHY driver to enable the RX and/or TX delays: - PHY_INTERFACE_MODE_RGMII should disable the RX and TX delay in the PHY (if required, the MAC should add the delays in this case) - PHY_INTERFACE_MODE_RGMII_ID should enable RX and TX delay in the PHY - PHY_INTERFACE_MODE_RGMII_TXID should enable the TX delay in the PHY - PHY_INTERFACE_MODE_RGMII_RXID should enable the RX delay in the PHY (currently not supported by RTL8211F) With this patch we enable the TX delay for PHY_INTERFACE_MODE_RGMII_ID and PHY_INTERFACE_MODE_RGMII_TXID. Additionally we now explicity disable the TX-delay, which seems to be enabled automatically after a hard-reset of the PHY (by triggering it's reset pin) to get a consistent state (as defined by the phy-mode). This fixes a compatibility problem with some SoCs where the TX-delay was also added by the MAC. With the TX-delay being applied twice the TX clock was off and TX traffic was broken or very slow (<10Mbit/s) on 1000Mbit/s links.
