    description
      "This module contains a collection of YANG definitions for
     supporting the Broadband Forum requirements on interface
     management as applicable to access network equipment. As such,
     this module is specific to access network equipment (e.g.,
     BBF-specified Access Nodes and FTTdp DPUs).

     Specifically, this module reports performance management of
     statistics defined by the IETF interfaces data model,
     ietf-interfaces (RFC7223).
