+  vBNG RFC2544 test case with QoS base line with link congestion.
+  Test case creates PPPoE sessions, runs traffic from two core ports
+  to one access port causing congestion of that port (traffic from
+  other access ports are splitting between remaining core ports)
+  and measures packets drop rate on all ports for each priority flow.
