Not really... I don't want this to be a system wide option, i need this to 
be able to generate some traffic under a certain pattern of packet sizes.

I really should read the code for more than 30 minutes... it's simple than i 
first think, i already have a simple patch for this, but it is too ugly for 
anything more than get iperf running...

This is the patch (just for reference - may work for someone else):
