Set Spanning Tree state.

        Args:
            enabled (bool): Is Autoupload enabled? (True, False).
            callback (function): A function executed upon completion of the
                method.  The only parameter passed to `callback` will be the
                ``ElementTree`` `config`.

        Returns:
            Return value of `callback`.
