Between the period of app_stop and app_start on the target device, target device choose to send ELS Reject for any receive AUTH ELS command. At this time, authentication application does not do els reject if it encounters error. Therefore, AUTH ELS reject signify authentication application is not running. If driver pass up the AUTH ELS Reject to the authentication application, then it would result in authentication application retrying/resending the same AUTH ELS command again + delay. As a work around, driver would trigger a session tear down where it tell the local authentication application to also tear down. At the next relogin, both side would be synchronize.
