I have:

EtherExpress PRO/100 S Server Adapter
Class 0200: 8086:1229 (rev 0d) Subsystem: 8086:1050
EtherExpress PRO/100B (TX) (MiniPCI Ethernet+Modem)
Class 0200: 8086:1229 (rev 08) Subsystem: 1668:1100

and I don't have this problem with rh 9 and 7.3 + kernel 2.4.20-13.x

an intel guy said that in l-k:

can you try turning off Rx checksum offloading in e100?  Set the module
parameter XsumRX=0 to turn it off.

2.2.21-k1 is pretty old version of e100.

Can we try the new e100-3.0.15?  Get it at 

This driver doesn't do hw checksum offloading, so I'm not expecting 
to see these errors.

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
