Thanks for this idea. I checked the kernel and set in
file smsc911x.c in function smc911x_reset()
	dev->dev_addr[0] = 0
to get valid (but not my mac address).

Nevertheless I would prefer to patch the uboot instead of kernel.
What I don't understand is: MAC (that is set in uboot - at least if I
do a tftp) will disapear.
Is it cleaned up by uboot? Somehow it has worked before ...

Or the other way around: What is the current valid and recommended way
to pass mac from uboot to kernel? It should work without patches.
