I would be interested in such a patch.
I'm trying to set up a testbed to see at what rates
ethereal and other libpcap sniffers start dropping packets
on various speed CPUs, but I don't have any good software
that allows sending at controlled rates.
Spending something like $10K on Ganymede/HP Chariot seems
like overkill(!) just to send traffic out at a controlled rate
for this experiment... so I guess I'll have to write somethin.
Pointers appreciated. I'll post results when there are some ;-).
