[c-nsp] Basic QoS on ATM subinterfaces

No, this won't work.  You've got several places you can apply the template:

-On the sub-interface
-On the PVC, with the outer shaper removed
-On the virtual-access (via the virtual-template)

If you're bulk-terminating a bunch of PPPoA sessions, I'd suggest that you want it applied to the virtual-access interface.  You can do this by either applying it to the virtual-template (if you're sure you always want the same policy for all the users), or push it back from RADIUS as a Cisco-avpair as each virtual-access interface is cloned.

Regards,
Tim.
