Program net device MAC addresses after initializing
Add a new function to the eth_device struct for programming a network controller's hardware address. After all network devices have been initialized and the proper MAC address for each has been determined, make a device driver call to program the address into the device. Only device instances with valid unicast addresses will be programmed.
