Re: [ECOS] Ethernet controllers..

[David Brennan <ecos at brennanhome dot com>]

I think you will run into this
(http://sourceware.org/ml/ecos-discuss/2004-11/msg00191.html) if you
attempt to instantiate two different Ethernet drivers based on the
eCos code. I never did need to actually do anything with this, so I
don't have any code to share. Of course since you plan on modifying
one of the drivers, you can modify the relevant parts of that as well.

Good luck.
