Hi Linus

You mention MDIO and PHYs, but the code is not there yet. When you do
add the needed code, it is a good idea to place the PHY nodes inside a
container node:

    ethernet@...09000 {
        compatible = "intel,ixp4xx-ethernet";
        reg = <0xc8009000 0x1000>;
        status = "disabled";
        queue-rx = <&qmgr 3>;
        queue-txready = <&qmgr 20>;

        mdio {
		phy0: phy@0 {
		      reg = <0>;
		};
	};
    };
