Error: unsupported driver sriov: invalid argument on Podman

[psaini79]

We are testing Mellanox driver on Podman and getting following error:

# podman network create -d sriov --subnet=192.168.0.0/20 -o netdevice=re0 -o prefix=roc mynet
Error: unsupported driver sriov: invalid argument

We are testing this configuration on following env:

Steps to reproduce:

1. Create the SRIOV based container:

podman run -d -v /var/run:/var/run --net=host --privileged rdma/sriov-plugin

2. Check the container:

podman ps -a
CONTAINER ID  IMAGE                               COMMAND               CREATED             STATUS                     PORTS       NAMES
e62d9ca88f4b  docker.io/rdma/sriov-plugin:latest  /bin/docker-sriov...  About a minute ago  Exited (2) 25 seconds ago              quizzical_bohr

3. podman images

REPOSITORY                   TAG         IMAGE ID      CREATED      SIZE
docker.io/rdma/sriov-plugin  latest      17072d351ad6  3 years ago  67.7 MB

4. Create the Bridge

 podman network create -d sriov --subnet=192.168.0.0/20 -o netdevice=re0 -o prefix=roc mynet

You will see the error on 4th step. Do we support Mellanox driver with Podman? If yes, please share the steps. If not, what is the ETA for the Podman support?
