Here's somebody on the web who had a very similar problem, with a
similar solution.

I wonder if your cable modem is using a larger MTU than ethernet has,
and is repacketizing your TCP stream along the way.  That would allow
it to send back-to-back packets out the Ethernet interface, which
would be the easiest way to confuse the NIC.  But repacketizing
IP is evil.

Just for a grin, before you shell out for a new NIC, why not try a
different release, such as KNOPPIX?  You can download it real fast
using Windows. (-:  Redhat may have introduced a driver bug.
