* General protocol hooks:
* ifa_notify Notify protocol about interface address changes.
* rt_notify Notify protocol about routing table updates.
* neigh_notify Notify protocol about neighbor cache events.
- * make_tmp_attrs Construct ea_list from private attrs stored in rte.
- * store_tmp_attrs Store private attrs back to the rte.
- * import_control Called as the first step of the route importing process.
+ * make_tmp_attrs Add attributes to rta from from private attrs stored in rte. The route and rta MUST NOT be cached.
+ * store_tmp_attrs Store private attrs back to rte and undef added attributes. The route and rta MUST NOT be cached.
+ * preexport Called as the first step of the route exporting process.
* It can construct a new rte, add private attributes and
- * decide whether the route shall be imported: 1=yes, -1=no,
- * 0=process it through the import filter set by the user.
+ * decide whether the route shall be exported: 1=yes, -1=no,
+ * 0=process it through the export filter set by the user.
* reload_routes Request channel to reload all its routes to the core
* (using rte_update()). Returns: 0=reload cannot be done,
* 1= reload is scheduled and will happen (asynchronously).
