Thanks Philippe,

I tried this patch and now I can see the rteth0 RUNNING (in rtifconfig).

Unfortunately, it doesn't change the rtping behavior (I still get the=20
=E2=80=9Cioctl: Resource temporarily unavailable=E2=80=9D message).

Best regards
St=C3=A9phane

The fec driver does not seem to tell the stack about the carrier enable=20
state. If so, you may want to try the following patch:

diff --git a/kernel/drivers/net/drivers/fec.c
b/kernel/drivers/net/drivers/fec.c
index 36870ba16..d94ec690f 100644
--- a/kernel/drivers/net/drivers/fec.c

 	rtnetif_start_queue(ndev);
 	fep->opened =3D 1;
 	return 0;
