Is it possible that someone changes manual at http://wiki.mikrotik.com/wiki/Manual:Queue to resemble syntax of MT v6.13?
Syntax (and way how MT handles queues) changed long time ago but manual still shows old syntax so it is unusable.
also, ‘pcq-limit’ and ‘pcq-total-limit’ are still described as “(in packets)”, but ther are actually in kilobytes
