-To program the device, the driver implements support for
-SWITCHDEV_OBJ_IPV[4|6]_FIB object using switchdev_port_obj_xxx ops.
-switchdev_port_obj_add is used for both adding a new FIB entry to the device,
-or modifying an existing entry on the device.
+To program the device, the driver has to register a FIB notifier handler

+FIB_EVENT_ENTRY_DEL: used for removing a FIB entry
+FIB_EVENT_RULE_ADD, FIB_EVENT_RULE_DEL: used to propagate FIB rule changes
