21  * \brief OpenNSL example application for Class Of Service module
22  *
23  * \details This example includes:
24  * o Port shaper
25  * o Queue's weight (WFQ)
26  * o Strict priority
27  * o Incoming TC/DP mapping
28  *
29  * It is assumed diag_init is executed.
30  *
31  * Settings include:
32  * Set the OFP Bandwidth to 5G using the port shaper.
33  * 1. Set the OFP Bandwidth to 5G using the port shaper.
34  * 2. Set queues priorities WFQ/SP as follows:
35  * - For the high-priority queues, WFQ is set: UC will get 2/3 of the BW and MC will get 1/3 of the BW.
36  * - For the low-priority queues, SP UC is set over MC.
37  * 3. Configure TC/DP egress mapping. Map low-priority traffic (0 - 3 for UC, 0 - 5 for MC)
38  * to low-priority queues, and high-priority traffic (4 - 7 for UC, 6 - 7 for MC) to high-priority queues.
