To Rick, maybe you can find a good solution or option with Eric's hint,
to send appropriate sized UDP packets with Don't Fragment (DF).
Well, I suppose adding another setsockopt() to the data socket creation
wouldn't be too difficult, along with another command-line option to
cause it to happen.
Could we leave things as "make sure you don't need fragmentation when
you use this" or would netperf have to start processing ICMP messages?
happy benchmarking,
