Hi Justin,

if you want to test, if the module works stable, run this script for one
or two hours. It will stress the driver and the hardware.

If it doesn't crash and if the throughput is stable, you can hope, that
the driver is ok for daily work.


#!/bin/sh

dest="server" # set the servername

while true ; do
netperf -t TCP_MAERTS -H $dest
netperf -t TCP_STREAM -H $dest
netperf -t TCP_SENDFILE -H $dest
done


Start the script on the client. On the server start netserver.
You get netperf from http://www.netperf.org/netperf/

Hello Andreas,

Thanks for the suggestion; however, it is crashing repeatedly after about 
5-10 minutes, so it is not needed yet.

Here you go, crash 2:
