-// Some confusing remarks about wNtbOutMaxDatagrams...
-//      ==1 -> SystemView packets/s goes up to 2000 and events are lost during startup
-//      ==0 -> SystemView runs fine, iperf shows in wireshark a lot of error
-//      ==6 -> SystemView runs fine, iperf also
-//      >6  -> iperf starts to show errors
-//      -> 6 seems to be the best value.  Why?  Don't know, perhaps only on my system?
-//      switch \a TU_LOG2 on to see interesting values for this.
