#dm raw mode brief
This will set the packet output to a more humanly readable format. 
Switch it back to normal to receive additional data.

#dm raw max 20
#dm raw
Raw packet debugging is on now

You packet output will follow. This is going to be everything hitting 
the cpu. Unfortunately there really isn't a way to get a more detailed 
view of what within the "IP" process is consuming cycles.

You can also use "#dm raw filter" to sift through the packets should 
that be necessary.
