+;; This example uses 2 physical ports, connected back to back or through a
+;; switch.
+;; The 1st physical port (DPDK port 0) generates (through tasks 2 and 3 on
+;; core 1) 2x IGMP membership query per second: one towards 224.0.0.3 and
+;; one towards 224.0.0.4.
+;; mcast packets can be generated using "speed 1 0 1" (to generate packets
+;; on core 1, task 0 at 100Mbps) and "speed 1 1 1" (to generate packets
+;; on core 1, task 1 at 100Mbps). They will resp. generate mcast packets
+;; towards 224.0.0.3 and 224.0.0.4;
+
+;; 2x VF are configured on the second physical port.
+;; They receive packets from the generator, each on their own mcast address.
