>Description:
NodeRunner NE2000 ethernet cards are incorrectly identified as NE1000
cards using the tests in if_ed.c. The cards will work as NE1000, but
the ethernet mac address is incorectly reported causing problems both
for the users, if more than one card reports the same address, and for
administrators (dhcp for instance will not work without a correct
mac address)
>How-To-Repeat:
All NodeRunner cards tried had this problem, and others on the net
have expressed this problem
>Fix:
Patchfile that works around problem, by disabling the NE1000 option
included (i.e. hacked file) I suggest improving the tests between
NE1000 and NE2000, or at least allowing the force 16bit option to work
for these cards#This patch was created 4/28/98 by Cory Zito, czito@nyx.net
#It's purpose it to kill the NE1000/NE2000 test forcing NE2000 to win
#This is needed for cards like ArtiSoft's NodeRunner, an NE2000 card
#that passes the NE1000 tests.
#
#Note: use patch -p0 < filename when feeding in this patch

> * the option between NE1000 and NE2000. This is a quick hack
> * that I did so DHCP would word since the ethernet address was
> * getting hosed by chosing NE1000. This patch is for 2.2.6, but
> * at least from 2.2.5 where I did this first, the commented lines
> * didn't change. Hopefully in the future the NE1000/NE2000
> * test will be fixed and this patch will not be needed. */
