[cisco-voip] LLQ Qn on policing

[Brian Meade]

Policing always applies even if no congestion.

You can set the exceed-action to remark DSCP and transmit.  There's also a
conform-action which just applies to burst traffic you can configure.
There's no upper limit if you configure the exceed-action to remark and
transmit.
