This is part of an RFC patch series introducing asynchronous platform data, which may be attached to discovered bus devices at probe time based on the device path. As part of the series, platform_data is enabled in usbnet layer. This patch used the usbnet platform data in the panda board definition file to set the MAC address of the USB <-> Ethernet onboard bridge to a unique value derived from unique CPU ID data.
