From: Fabio Estevam festevam@denx.de
Currently, only the first MAC address is read from the fuses.
The second MAC address is not read and Linux assigns a random one.
To prevent this behavior, read the second MAC address from the fuses and store it into the eth1addr environment variable so that it can be passed to Linux.
