Ok, i was just wondering if Linux try to access to the environnment variable
"ethaddr" to get it's value (i've forget one or two words in my question and
i ask you to excuse me for that)
but to access to ethaddr, someone say me that i can modify the Linux driver
to catch the ethaddr by a custom option in my bootargs
