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.
