how to cross-compile netperf.

[Ming Liu]

Dear Wolfgang,
By the Way, another problem now. If I transfer UDP packets from my PC to my 
board as "netperf -H 192.168.0.5 -t UDP_STREAM -l 30", a problem happens on 
my ML403 board and ppc 405 as:

If I specify the time length shorter, e.g. -l 5, it will not happened. 

This never happens when using TCP.

Can anyone tell me what's the reason and how to solve this? thanks for your 
helping.
