 1. Read from hardware in initialize() function
 2. Read from environment in net/eth.c after initialize()
 3. Give priority to the value in the environment if a conflict
-4. Program hardware in the device's init() function.
+4. Program the address into hardware if the following conditions are met:
+       a) The relevant driver has a 'write_addr' function
+       b) The user hasn't set an 'ethmacskip' environment variable
+       c) The address is valid (unicast, not all-zeros)

-in the board-specific board_eth_init() function by calling eth_init()
-after all the NICs have been registered.
