Hello Alec, I am working on taking account your comments but I have one question about retrieving source mac address in end-to-end connectivity check.
I used Scapy library to identify source mac address from packet received by traffic generator and for VLAN use case no need to use binary block and choose the good offset. Scapy Ether class no need to specify some offset and seems transparent to Ethernet encapsulation. I was not able to test VXLAN use case on our platform but I hope Scapy is also able to retrieve mac source address in this case. Have you the possibility to test this part on your side ? or do you prefer to keep using binary packet and offset as before ?

This basically splits the code into several parts: * the part that handles traffic on the packet path (including ARP, IP addresses…) which works with any mode (EXT, PVP, PVVP) * the part that creates/reuses devices (openstack case only: PVP. PVVP): neutron routers, extra networks… We can limit this first version of the feature to single-chain/VLAN and see later whether there is interest in extending to multi-chaining and to VxLAN. Perhaps add some description on why this feature can be useful or what kind of problems/requirements it will address.

I hope this fits with your design approach ☺ Be welcome to ask me if something is not clear to you. For now I only manage 1 PVP chain with neutron routers as loop VM can be enlarge and fit our use case. Let me know if you think multi-chains is required for this type of traffic.
