Description of problem:
This is a similar problem to those reported for RedHat 7.1 (bug #37454) and and
for RedHat 7.2 (bug #63071)
I am using a Xircom CBEM56G on a Dell Latitude C800 under RedHat 8.0 and
experiencing a very slow network connection since the RH 8.0 installation.
The network worked great with my previous linux distro (kernel 2.4.18 without
pcmcia support and pcmcia-cs 3.1.?)
The default installation correctly recognizes the net card but I have a
maximum throughput of 10 Mb/sec (being connected to a 100 Mb switch)
The workaround detailed in bug #63071 worked for me.
After modifying the config as explained and rebooted, I have a full 100 Mb/s
throughput again !
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Install redhat 8.0 - default options - using a Xircom CBE56G pcmcia card
2.test the network performance (netperf)
Actual Results: networking is very slow (throughput < 10 Mb/s)
Expected Results: Actual throughput must be around 100 Mb/s
workaround described in bug #63071 worked for me and restored my expected throughput
