Detailed Description

mq is a classful multi-queue aware dummy scheduler.

Introspection did not find any typical Config paths.

It has as many child queue discs as the number of device transmission queues. Packets are directly enqueued into and dequeued from child queue discs.

No Attributes are defined for this type.
