Patch from Emmanuel Raguet <raguet@crf.canon.fr> to correct some problems

in the dec21140 driver.  Comments follow:

    I have tried to use bootp with the dec21140 driver
    and I had problems. I have found them
         - Ethernet address must be known in Attach step
           (read from the board)
         - Endian problem for Ethernet address storage.

    Now it is solved and I can use bootp to obtain
    the network configuration of the target.
