      Description of problem:

      When trying to initialize Mellanox MT2910 ConnectX-7 nic in InfiniBand mode using the Config from our documentation it fails to get initialized. The device is discoverable as seen in sriov-network-config-daemon logs but it dosen't gets added to resource list for device-plugins to advertise

      Version-Release number of selected component (if applicable):

      SR-IOV operator on OCP v4.16

      How reproducible:

      Happening with InfiniBand mode

      Steps to Reproduce:

      1. Try creating SriovNetworkNodePolicy using linkType: ib
      2. We can straightaway use the one mentioned in examples of documentation.
      3. Check the the sriov-network-config-daemon pod logs.
          

      Actual results:

      The VFs are discovered but not added to the new created resource

      Expected results:

      The VFs should be initialised & advertised by device-plugin pods

      Additional info:

      Although the NIC being used is a supported one, when appling policy it returned --> no supported NIC is selected by the nicSelector. So, I asked them to disable OperatorWebhook & then enable Developer mode to see if it helps in the process of initialization as a part o just testing.
