Reconcile loop runs on every node update notification, which is not necessary and can lead to a large number of produced log lines per hour, even if the operator is idle.

E.g. after 1h of idle time:

$ grep "INFO     SriovNetworkNodePolicy  handler/eventhandler.go:97      Enqueuing sync for create event" openshift-sriov-network-operator-pods_logs.log| wc -l
526

    1. Install the operator 

cat << EOF | oc create -f -
apiVersion: v1
kind: Namespace
metadata:
  name: openshift-sriov-network-operator
  annotations:
    workload.openshift.io/allowed: management
  labels:
    pod-security.kubernetes.io/audit: privileged
    pod-security.kubernetes.io/enforce: privileged
    pod-security.kubernetes.io/warn: privileged
EOF

operator-sdk run bundle \
    registry.redhat.io/openshift4/ose-sriov-network-operator-bundle:v4.18.0.202502260933.p0.gf496851.assembly.stream.el9 \
    --namespace openshift-sriov-network-operator
    2. Configure the SriovOperatorConfig with default values
cat <<EOF | oc create -f -
apiVersion: sriovnetwork.openshift.io/v1
kind: SriovOperatorConfig
metadata:
  name: default
  namespace: openshift-sriov-network-operator
spec:
  enableInjector: true
  enableOperatorWebhook: true
  logLevel: 2
  disableDrain: false
EOF

    3. Wait few minutes
    
    4. Check how many times the SriovNetworkNodePolicy reconcile is called
$ oc get  -n openshift-sriov-network-operator pods | grep sriov-network-operator; oc logs -n openshift-sriov-network-operator deploy/sriov-network-operator | grep 'Reconciling.*{"controller": "sriovnetworknodepolicy"' | wc -l
