-     * The priority value is used when issue uid ranges rules to netd. Netd will use the priority

-     * Thus, any device originated data traffic of the applied uids can be routed to the altered
-     * default network which has highest priority.
+     * For per-app preferences, requests contain an int to signify which request
+     * should have priority. The priority is passed to netd which will use it

+     * to direct device-originated data traffic of the specific UIDs to the correct
+     * default network for each app.
+     * Priorities passed to netd must be in the 0~999 range. Larger values code for
+     * a lower priority, {@see NativeUidRangeConfig}
      *
-     * Note: The priority value should be in 0~1000. Larger value means lower priority, see
