Well, as you may guess I have echo replies working, so the server can now be
pinged :)
Oh, and this might be interesting... Top is our new "stack", below is
existing net_server.
.133 is a tulip card under our stack, .134 is a 3Com under net_stack, in the
same machine, pinged from the same machine (FreeBSD 4.4) over a 100Mb
half-duplex network. Worth noting is that the net_server results don't show
the initial delay of dealing with an arp cache as this was the second
attempt in under 20 minutes so the value was already stored. In our results
the initial delay is us sending/processing the arp request :)
And now, without further ado, the results...

Now, I'd like to ask everyone with a degree of knowledge of C to go through
the code and look at whether it can be improved (I know it can be). Why now?
This is probably as fast as the stack will ever go and changes now gain us a
lot. Also the code we have will more than likely be used as templates for
what follows, so we get this right and what follows will be better :)
