Sometimes interface updates could happen in a way ifnotifier is not able to catch. For example some heavy operations (device reset) in netdev-dpdk could require re-applying of the bridge configuration. For this purpose new manual notifier introduced. Its function 'if_notifier_manual_report()' could be called directly by the code that aware about changes. This new notifier is thread-safe.
