      Description of problem:

      If policies are unsorted, it can result in a termination loop for the daemonset pods.

Currently being worked on upstream under https://github.com/k8snetworkplumbingwg/sriov-network-operator/pull/721

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

      v4.14.0-202406060838

      How reproducible:

      Steps to Reproduce:

          1. Provision a cluster with a non-trivial number of SRIOV  nodes (> 6)
    2. Install the SRIOV network operator
    3. Create 10+ SriovNetworkNodePolicies using different values for `.spec.nodeSelector`

      Actual results:

      sriov-device-plugin daemonset pods enter a termination loop

      Expected results:

      sriov-device-plugin  daemonset pods enter a running state
