You didn't say what kind of ethernet board you're using. If you're
using a 3COM 3C501, expect to lose lots of packets. The 3C501 is a
dog.  Architecurally, it's the same as the very first ethernet card
available for PC's (the 3C500), and has only a single packet buffer,
so the receiver must be disabled while loading the buffer for
transmit, and you cannot receive back-to-back packets (or anything
even close to them).

Granted, the TCP shouldn't cause a panic under any circumstances, but
for years, th e 3C501 has been a leading cause of poor performance...
