Latest cobalt updates

[George Amanakis <g_amanakis@yahoo.com>]

Dear Jonathan,

I am looking/testing the latest cobalt updates.Most of them make sense. 
I have a question though.
At the end of cake_dequeue() you schedule the watchdog at 
"now+q->tins[i].cparams.target" if "!sch->q.qlen". This seems very 
reasonable. Instead in the beginning of cake_enqueue() you do:

  916                 if (!sch->q.qlen) {
  917                         if (q->time_next_packet < now) {
  918                                 q->time_next_packet = now;
  919                         } else if (q->time_next_packet > now) {
  920                                 sch->qstats.overlimits++;
  921 #if LINUX_VERSION_CODE < KERNEL_VERSION(4, 8, 0)
  922 codel_watchdog_schedule_ns(&q->watchdog, q->time_next_packet, true);
  923 #else
  924 qdisc_watchdog_schedule_ns(&q->watchdog, q->time_next_packet);
  925 #endif
  926                         }
  927                 }
  928         }

Is there any reason why you haven't scheduled the watchdog at 
"now+q->tins[i].cparams.target" like in cake_dequeue()?

Thank you,
George
