[RFC PATCH 2/3] USBNET: Introduce usbnet platform data

[Andy Green <andy@warmcat.com>]

This defines optional platform_data for usbnet.  It allows
you to force eth%d name usage based on board-level knowledge
that it is soldered to a board and wired to an RJ45 on the board,
and to set the MAC address to a specific value from board
definition file.
