* generic list routine. We expect objects in a specific order, i.e. * PIPES AND SCHEDULERS: * link; scheduler; internal flowset if any; instances * we can tell a pipe from the number. * * FLOWSETS: * flowset; queues; * link i (int queue); scheduler i; si(i) { flowsets() : queues } */

 * link i (int queue); scheduler i; si(i) { flowsets() : queues }
