Hi,

I'm trying to troubleshoot QNX 6.4.1 running inside a VirtualBox 3.0.6 VM. I'm using the pcnet AMD lance driver. To make
 make matters worse I'm on Mac OSX 10.5.8 (x86). 

But the question itself is rather general: What is the toolset for troubleshooting driver issues:

1.) tcpdump -e -i en0 -vv
2.) nicinfo

what else could i do to monitor activity, get status, etc? Since the pcnet driver doesn't seem to be part of the source 
package, i couldn't build a debug version ...

cheers,

Matthias
