[j-nsp] Network-control queue counter increases on ccc-configured interface

[Keegan Holley]

You said this is a ccc interface.  Is the customer connecting to this
device through this interface or is this part of a L2 circuit that
traverses this interface.  If it is the latter, they could be running
a protocol over the circuit that is being placed in your NC queue.
Also, how long did it take to increment?  If it only logged 832
packets in a few hours or days I'd ignore it.  Reconfiguring qos
without understanding the traffic flows may be worse.
