+# A test for strict prioritization of traffic in the switch. Run two streams of
+# traffic, each through a different ingress port, one tagged with PCP of 1, the
+# other with PCP of 2. Both streams converge at one egress port, where they are
+# assigned TC of, respectively, 1 and 2, with strict priority configured between
+# them. In H3, we expect to see (almost) exclusively the high-priority traffic.
+#
+# Please see qos_mc_aware.sh for an explanation of why we use mausezahn and
+# counters instead of just running iperf3.
