Hm... Note that such code will probably not go into mainline. The
principle in U-Boot is not to initialize any devices that are not
used by U-Boot itself, so unless you use a network related command in
U-Boot, none of the Ethenret interfaces shall be initialized; and
U-Boot never uses more than one at a time in any case.

NAK. This will not go into mainline.

There are three ways to get something done:
        (1) Do it yourself.
        (2) Hire someone to do it for you.
        (3) Forbid your kids to do it.
