"This module contains a collection of YANG definitions for
supporting the Broadband Forum requirements on the management of
Quality of Service (QoS) 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 contains a collection of policies
applied to packets.

"Interfaces that can have QoS policy profiles assigned.
If several interfaces linked by a parent-child
relationship in the interface stack are configured with
a QOS policy of the same type (e.g. ingress-qos-policy),
then all QOS policies must be applied sequentially.
In the case of ingress, the QOS policy on the lower-level
interface(s) (e.g. ethernetCsmacd) must first be applied before
the one on the upper-level interface(s) (e.g.
vlan-sub-interface).
In the case of egress, the QOS policy on the upper-level
interface(s) (e.g. vlan-sub-interface) must first be applied
before the one on the lower-level interface(s) (e.g.
ethernetCsmacd).";
