So it is not too bad ... if you take protocol overhead into account I am
getting >7mb on a 10mb ethernet using a Netgear tulip clone board with
linux-2.2.14 + the ide patches.

Differences in speed might be due to other network activity going on at
the time.

Also note that the kernel is stripped of things like firewalling.
masquerading, etc.
