You can "setenv ethaddr *****" under u-boot or set random address on
kernel ether driver.

This is VERY BAD advice. NEVER, NEVER EVER use random MAC addresses.

The address is typically programmed into the deivce. In U-Boot,  just
type "printenv ehtaddr" to display the current setting.

"Double kick"? This is qualtiy software which is not  used  to  being
kicked. It simply refuses to work under such rough treatment.

Be friendly, and just call the applicatioin by it's name:

	-> cd tools
	-> ./gen_eth_addr
	3e:55:7a:55:ef:d3
	-> ./gen_eth_addr
	de:b0:7f:c9:4e:a9
	-> ./gen_eth_addr
	9a:17:0d:df:1f:4a

There you go...
