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

Which architecture are  talking  about?  And  what  exactly  is  your
problem?

U-Boot passes arguments in registers; some  of  these  registers  may
contain  pointers to things like the board info data (struct bd_info)
or the kernel commandline or a flattened OF device tree or ...
