This counter tracks how many packets have been successfully received and forwarded for a specific receive-priority queue, letting an administrator see actual traffic volume flowing through each priority level. Comparing this counter across different receive priorities helps an admin verify that priority mapping is working as expected and that high-priority traffic like voice is actually being counted separately from best-effort data. For example, a steadily climbing count on the highest-priority queue while voice calls are active would confirm that voice traffic is correctly landing in that priority level.
