    description
      "This module adds configuration and operational state relating to
       policies for traffic destined to the system's control-plane.
       Particularly, it allows for mechanisms to:
        - apply an ACL that forwards or drops traffic towards the control-plane.
        - classify traffic that is destined to the control-plane according to
          a QoS classifier.
        - schedule traffic that has been forwarded towards the control-plane,
          to allow for policies such as rate limits to be applied.
       The configured policies apply generically to all control-planes that
       exist within the system, and should be mapped to the internal interfaces
       via which packets are forwarded to control-plane modules.
       When a packet is received at an input interface - it is classified into a
       forwarding group which drains to a specific queue. If this input mapping
       is sufficient, the CPU-facing interface uses the specified scheduler
       to determine how to drain queues. If more granular remapping is required
       (e.g., to classify control-plane traffic more granularly), a user specifies
       an alternate classifier that is used to reclassify traffic into
       a new set of forwarding-groups (and hence queues) that can subsequently
       be scheduled by the specified scheduler.
       The specified control-plane ACL is applied to traffic received by the
       control-plane of the system.";
