Detailed Description

Thread-safe packet queue.

It can operate in one of these modes:

• plain mode: packets are dequeued as fast as possible.
• delay mode: packets are dequeued no earlier than q->target after it's received.
• CoDel mode: PktQueuePopResult.drop is set according to CoDel algorithm.
