The implementation of ReconcileAntreaConfigDataValue should also be modified to pass Antrea-NSX configs to values.yaml like below:

antrea:
  # … antrea related configs
antrea-nsx:
  enable: true    # set the values according to AntreaConfig.spec.antreaNsx.enable
  bootstrapFrom:  # bootstrapFrom either providerRef or inline configs
    providerRef:    # set the values when Antrea-NSX is bootstrap from NSXServiceAccount. Fill the NSXServiceAccount name created by addon controller to below resource name.
      apiVersion: nsx.vmware.com/v1alpha1
      kind: NSXServiceAccount
      name: test-cluster1-antrea
    inline:  # set the values according to AntreaConfig.spec.antreaNsx.bootstrapFrom.inline is set
      nsxManagers: [sampleNSXIP1, sampleNSXIP2, sampleNSXIP3]
      clusterName: test-cluster1

Antrea Package needs to be updated to support the new fields in values.yaml, too. I'm now sure if existing Antrea Package can ignore these new fields. We can have a try on manually editing the values.yaml in workload cluster and see if Antrea PackageInstall reconciles successfully.

According to our offline discussion, we add -antrea to the resource names.
So the here it should be changed to:

nsxSAName := clusterName+"-antrea"
nsxSecretName := clusterName+"-antrea-nsx-cert"
providerServiceAccountRBACRules := []rbacv1.PolicyRule{
  {..., ResourceNames: []string{nsxSAName}, ...},
  {..., ResourceNames: []string{nsxSecretName }, ...},

I think it's better to put the cert and key in a Secret, so it's flexible to set different RBAC rules for AntreaConfig and Secret. For example, we can have a role which can view and create AntreaConfig, but the role cannot read the Secret.

So here the NsxCertRef can be just a string, the value is the name of the Secret. We can rename this field to NSXSecretName.
