The data ports of the VM are on port 35 and port 36 on br-int, VM also has a port we use for access and is on port 34.

each of the two VM data ports is on its own provider network, with vlan 300 and 301; there is another VM port (port 34 on br-int) is for VM access with vlan 200 and not used for data traffic.  The VM simply switch the packets between its data ports.

The traffic generator has two ports, with mac address ec:f4:bb:dc:93:98 on port 1, ec:f4:bb:dc:93:9a on port 2. port1 send udp traffic destined to port2's mac and vice versa.
We expect the traffic from its port1 to reach the br-int port 35 and then switched by the VM and come back on port 36 and go to 
port 2 of the trafficgen.
