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
