+   * Pipe stats (as anything related to pipes) are a bit tricky. There
+   * are two sets of stats - s1 for routes going from the primary
+   * routing table to the secondary routing table ('exported' from the
+   * user point of view) and s2 for routes going in the other
+   * direction ('imported' from the user point of view).
+   *
+   * Each route going through a pipe is, technically, first exported
+   * to the pipe and then imported from that pipe and such operations
+   * are counted in one set of stats according to the direction of the
+   * route propagation. Filtering is done just in the first part
+   * (export). Therefore, we compose stats for one directon for one
+   * user direction from both import and export stats, skipping
+   * immediate and irrelevant steps (exp_updates_accepted,
+   * imp_updates_received, imp_updates_filtered, ...)
