Linux pfifo_fast is the default priority queue enabled on Linux systems.
Packets are enqueued in three FIFO droptail queues according to three priority bands based on the packet priority.
The system behaves similar to three ns3::DropTail queues operating together, in which packets from higher priority bands are always dequeued before a packet from a lower priority band is dequeued.
The queue disc capacity, i.e., the maximum number of packets that can be enqueued in the queue disc, is set through the limit attribute, which plays the same role as txqueuelen in Linux. If no internal queue is provided, three DropTail queues having each a capacity equal to limit are created by default. User is allowed to provide queues, but they must be three, operate in packet mode and each have a capacity not less than limit.
