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.
