This read-write object controls saving and loading of the TCP module's configuration information, and its value also reports whether a save or load operation is currently in progress. Admins set it to trigger persisting the current TCP settings, such as usrTcpMaxConn or usrTcpNagleStatus, to the config file, or to reload previously saved settings, and can poll it to confirm the operation completed. For example, an admin sets usrTcpCFMStatusFlag to a save value after changing usrTcpMaxConn, then polls it until it reports idle to confirm the new connection limit was written to the config file.
