Looking at net-next, I think there's more to be fixed here:

        case PHY_INTERFACE_MODE_RGMII:
        case PHY_INTERFACE_MODE_RGMII_ID:
        case PHY_INTERFACE_MODE_RGMII_RXID:
        case PHY_INTERFACE_MODE_RGMII_TXID:
        case PHY_INTERFACE_MODE_SGMII:
...
		phylink_set(mask, 10000baseT_Full);

Is that really true?
