 Hi,
   newbie question. In sch_htb.c:htb_dequeue() there is a comment "try
to dequeue direct packets as high prio (!) to minimize cpu work". Does
that mean that any unclassified packet (no class/filter applicable) is
scheduled as the highest priority packet in HTB? If yes, what is the
reason that the direct queue is not treated as the lowest priority
best-effort?
TIA for any info.

Yes, unclassified traffic is dequeued at hardware speed bypassing any defined qdiscs. It is up to you to specify default class and make it low prio. Right now i can't thnik of any reason for that behavior.
