Yes ! We are neighbour :)
Free Electrons, I know you by name. And the kernel sources on your web 
site help me a lot !

It is a "home-made" board with a iMX27.

Hum, I did not configured it myself. I used a previous configuration of 
the board which was :
"
static struct fec_platform_data fec_info = {
	.xcv_type = MII100,
	.phy_addr = 1,
};"

How can I know which address I need to put ?

Sorry for, maybe, "newbie" question but I am self-taught in kernel 
development.
