Both ports can receives packets from one port and sends to the other = port. Previous I assign 2 Mellanox CX4 Lx VF to achieve, but after I change to = use X520(82599ES controller) VF in recently days, my program is unable = to receive and send packets anymore. I also already tried to use Intel X710 VF on another server, and then it = works but at that server, hardware resource is running out. Therefore I = cant use that server to do more tests. Now the Mellanox CX4 NIC is connected to the other environment and is = unused, and due to the COVID-19 lockdown issue I can't change the link = topology. Does anyone know this issue? Thanks, BR, Huai-En=
