[c-nsp] Strange behaviour with 6509

"show proc cpu" is telling you the load of the MSFC in your 6500.  
Having a low utilization is a good thing, since it means that the 
hardware is moving your packets.

The problem is that there is no good way to see the total utilization 
of your PFC's and DFC's.  A "sho mls stat" will give you the PPS rate 
for L3 forward packets, but not L2 switched packets.  Also it won't 
give you the relative utilization, so you would have to calculate that 
relative to the performance ability of the PFC/DFC you are using.
