To change the MAC addresses, only the environment
needs to change as follows ...

u-boot> setenv ethaddr <valid MAC address>	(eth0)
u-boot> setenv eth1addr <valid MAC address1>	(eth1)
u-boot> setenv eth2addr <valid MAC address2>	(eth2)
u-boot> saveenv

Omit references to eth1 or eth2, if they don't exist
on your specific board.

There is no need to recompile U-Boot.
