Re: [LARTC] What is drop in Qdisc_ops for?

Chris,

Have you discovered the following source of documentation on the QoS
APIs for linux, yet?

  http://qos.ittc.ukans.edu/howto/index.html

 : What is the operation drop() in Qdisc_ops for?

Well, from the userland perspective, drop is just like a netfilter -j
DROP.  Essentially we are saying "throw that packet away".

 : What are the requirements on a new qdisc?

/me retreats to userland, maybe the link above will provide an answer.

 : As far as I can tell, the classfull qdiscs just pass it on to child
 : qdiscs and classless qdiscs drop the most recently queued packet. I
 : can't find any code that initiates all this though.

Again, try the above documentation.

 : The operation is not described in the comments in sch_api.c where
 : enqueue, dequeue, requeue, reset, init, destroy & change are described
 : (dump isn't described either).

Here's a little bit on dump.

Good luck,
