     * @group:       	4.7 Audio Video Bridging and Time Sensitive Networks
     *
     * @description:	AVB defines a set of features and protocols for ensuring high QoS for time-sensitive traffic such as audio and video
     * 					streams. The device provides the necessary hardware features for implementation of AVB: gPTP timing synchronization
     * 					features (802.1AS, based on 1588 PTP), prioritized queuing, and credit-based traffic shapers (802.1Qav). Ports sup-
     * 					porting AVB must operate at 1000 or 100 Mbps at full-duplex. 10 Mbps and/or half-duplex are not compatible with AVB.
     * 					Non-AVB devices are not allowed to participate in an AVB network, but non-AVB traffic is allowed to occupy available
     * 					bandwidth unused by the AVB traffic. Protocols are defined for network discovery, path setup, and bandwidth reservation
     * 					across the network.
     * 					AVB defines Stream Reservation (SR) traffic classes, which are given a high priority for queuing and egress scheduling.
     * 					With up to four egress queues per port, the device can accommodate up to two SR traffic classes. Ingress AVB traffic
     * 					packets are typically VLAN tagged. If not, the device can assign them a customizable VLAN tag on a port-by-port basis.
     * 					The information in this tag, including the 3-bit PCP priority field, is used to map the packets to the appropriate high pri-
     * 					ority queue. At least one queue must be reserved for non-SR traffic classes, in order to accommodate regular “best
     * 					effort” network traffic.
     * 					The egress of SR class traffic from the high priority queue(s) is regulated at each queue by a credit-based traffic shaper
     * 					as discussed below. If the SR traffic streams do not exceed their reserved bandwidth, then the traffic shaper will ensure
     * 					that the packets egress in a relatively uniform manner.
     * 					The 802.1AS standard, which ensures node synchronization in an AVB network, relies heavily on the IEEE 1588 stan-
     * 					dard for PTP. It defines a specific profile for 1588, and adds certain other requirements in the context of 802.1Q. The
     * 					resulting entity is referred to as generalized PTP (gPTP). Section 4.6, "IEEE 1588 Precision Time Protocol" discusses
     * 					IEEE 1588 and 802.1AS together.
     * 					The device provides two egress traffic shaping options. The IEEE 802.1Qav Credit-Based Traffic Shaper provides traffic
     * 					shaping as defined in IEEE 802.1Qav. This is configurable on a per-queue basis. Each port also has a Time Aware Traf-
     * 					fic Scheduler (TAS) that provides periodic timing windows for transmission of time sensitive traffic class data. The
     * 					shaper and scheduler options and details are individually configurable for each egress port.
