Not obvious, but I have already implemented that. I actually added some stuff 
so that I could send the stats variables over the Ethernet connections as well. 
Unfortunately, there isn't really enough info in the stats to indicate what is 
going wrong.

I do get a few received packets with erroneous protocols, but these don't seem 
to be related to the problem.

Invoking any of the lwIP printf functions reduces throughput on my system a 
bunch. Printf and the UART just aren't as fast as the Ethernet.
