Hi,

My U-Boot already has a ethaddr defined. It's what is used by the
default kernel that came with the board (3.2).

U-Boot# printenv
[...]
ethaddr=d4:94:a1:8b:ec:78

The problem is that this is ignored by the latest kernel and it
replaces it with some random mac.

Note, I boot via bootp, thus it has to have a mac. That mac is what
tells my dhcp server what kernel image to load this board.
