+In this testsuite, TRex is used to generate Uplink GTPU traffic on the RAN side
+towards UPF on its 1st iface and which which should be sent back decapsulated
(tunend) towards CN and received at TRex 2nd interface.
+
+The GTPU traffic is generated by gtp_1pkt_simply.py profile passed to TRex,
+which emulates <enb-ip-addr,TEID> sessions based on parameters passed through
+trex-console when launching the test, and which should match those configured
in
+cpf/0.gtp_flood.vty used by osmo-upf-load-gen to allocated the sessions at the
+UPF.
