Problems with 3c575 cardbus on RedHat 5.1, pcmcia-cs-3.0.3

[Peter Mardahl]

Hello, 

  I'm getting errors on my 3c575 cardbus when operating
100MHz/FD.  It's impacting my performance, I'm hoping
someone can please help me....

This is the driver I'm using:
Jul 21 13:56:21 vlasov kernel: 3c59x.c:v0.99 4/7/98 Donald Becker http://cesdis.gsfc.nasa.gov/linux/drivers/vortex.html

Kernel 2.0.34, RedHat 5.1, pcmcia-cs-3.0.3.

I modified the driver to FORCE 100MHz operation:  I can't use
autonegotiation here:  I only added lines like

  vh->full_duplex = 1;

  in places after it would check "options".  There were problems
before, also, when I was not FORCING full-duplex and it was
reporting half-duplex.

Here is some debugging info:
