* ethaddr: Ethernet MAC address for first/only ethernet interface
(= eth0 in Linux).
This variable can be set only once (usually during manufacturing
of the board). U-Boot refuses to delete or overwrite this variable once
it has been set.
* eth1addr: Ethernet MAC address for second ethernet interface (=
eth1 in Linux).
* eth2addr: Ethernet MAC address for third ethernet interface (=
eth2 in Linux).
Some assembly may be required: we don't know _your_ board, _you_ may
have to implement the routine that actually stores the MAC in your hardware.
