Hi qian,
Could you add this test in execution.conf and execution_FVL.conf for Niantic and FVL NIC test?
Thanks a lot

> 1. Support FVL 4x10g, 2x10g, 2x40g.
> 2. Update the traffic to make the MAC address and VLAN id changes together.
> Then the packet loss is 0 at low traffic.
> 3. Set the max pools number for major NICs: FVL 40G, 10G, Niantic, 1G.
> 4. Update the core config.
