[vortex] Test results with 3c90xcfg -- I'M CONFUSED!

Fri Feb 22 19:22:01 2002

This will be a long message.
I have MANY dumps with an ongoing narrative of what was done.
Summary: The more I learn the more confused I get.
I set 100Base-T FullDuplex with the 3c90xcfg utility, and it behaved
as if I'd set HALF duplex!

I was unable to reproduce the athenaphobia failure mode.
I am hopeful that this output will help you understand what's up.

-wdc

P.S.  I edited out the ^@ that gets reported by diag for division and product
which will enable emacs and diff to perceive the output as a text file
instead of a binary file.

---- enclosure: massive testing logs ----

Tokata:

(I hope running with stock 1.1.16 is ok)

Powered up, and found itself in an unhappy state as shown
by transfer time via wget of a 2.5MB file:

It occurred to me that perhaps there was an interaction
between the 1.17 driver and the EEPROM writeout.
So I got vortex-diag -eav after changing over to
the 1.17 driver and power-cycling.  I expected the
output to be the same.  IT WAS NOT!

And back to autonegotiate as set by 3c90xcfg
(Note:  THis time I took an alternate path 
through the UI. Instead of the AUTOCONFIG choice,
I tabbed into the NIC parameters and chose
Autoconfig (N-WAY) for speed.  It then set
Autoconfig for Duplex.

I've booted up, and the network feels happy:
