Description of problem:
Upgrading to kernel-2.4.3-12 causes my Xircom CardBus ethernet 2 100Mbps to
fail to operate under Full Duplex mode.  The network still works, but some
services do not work properly.  Most notably, a cvs client on this machine
fails intermittently.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. upgrade from kernel-2.4.2-2 to kernel-2.4.3-12
2. reboot with xircom cbe2 in pcmcia slot
3. watch network switch or hub light indicate link is not running in full
duplex mode
	

Actual Results:  Services which require full duplex don't work, or work
sporadically.

Expected Results:  Should operate in full duplex mode.  kernel-2.4.2-2
worked fine

Additional info:

Here's my /var/log/messages output for kernel-2.4.2-2 (where full duplex
works fine):
