Optional report callback function pointer for all routes.
Note
The passed result callback function does not only report the result of the build operation but also monitors the status of the created routes during their whole lifetime. That is, the callback function also reports the various states of a route (Refer to Ucs_Rm_RouteInfos_t for more infos). Furthermore the result of Ucs_Rm_SetRouteActive() function call is reported by this result callback function.
