The FIFO qdisc comes in two flavours:
More...
- bfifo (Byte FIFO)
- Allows enqueuing until the currently queued volume in bytes exceeds the configured limit.backlog contains currently enqueued volume in bytes.
- pfifo (Packet FIFO)
- Allows enquueing until the currently queued number of packets exceeds the configured limit.
The configuration is exactly the same, the decision which of the two variations is going to be used is made based on the kind of the qdisc (rtnl_qdisc_set_kind()).
