the fxp has a problem which does not allow it to go above 103/110/120kpps
depending on which descriptor model you use, no matter how fast
the CPU is.
Even not using any special kernel modules, a simple loop over
a sendto() on a udp socket can achieve around 500kpps on a 2.4GHz
box (em or bge). With some tricks and a sufficiently fast PCI
bus you can reach some 750kpps but then it really depends
on how fast is your PCI bus.
