[nsp] diagnosing dCEF

[Kenny Stoltz]

I have a 7500 that has "ip cef distributed" enabled, and even though 
this is turned on show interfaces switching produces output like

What is the easiest way to diagnose why dCEF isn't switching any packets 
and IP Process is switching such a massive amount of packets?
