[c-nsp] 7206VXR and CBWFQ

I believe the priority queuing can only be applied to a main interface,
not a subint.  Create a second policy, and do the priority queuing on
that one, and apply that to the main int.  The VOIP class/policy can
remain on the subint.  I'm not totally sure about ATM, but that's how
I've seen it work on Ethernet.

 Whenever I try to apply the following I get an error message about how
CBWFQ can't be applied to subinterfaces.  What is the correct way to do
