@@ -9,10 +9,26 @@ The following properties are common to the Ethernet controllers:
- max-speed: number, specifies maximum speed in Mbit/s supported by the device;
- max-frame-size: number, maximum transfer unit (IEEE defined MTU), rather than
the maximum frame size (there's contradiction in ePAPR).

- phy-handle: phandle, specifies a reference to a node representing a PHY
device; this property is described in ePAPR and so preferred;
