Subject: Questioning about DM9000 and link up delay

Hello everyone,

I am working on a fast boot project and i have a "trouble" and i would
know if someone know more about this topic.

I have improve my boot time . But now i would like to add dhcp
capacity and i have a delay (~2 sec) between dm9000 loading and link
up message. I use kernel ip autoconfig (ip=dhcp on boot cmd) to get
the IP adress.

I have try lot of things (Force media type, trace initcall, etc), but
i cannot find the source of this delay. I think it's a hardware delay,
but 2 second sound like to much for me.

Have you any idea where i can search ?

Hardware configuration :

Mini2440 board
Linux 2.6.32.2
DM9000 driver

Thanking you in advance.
