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 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
