Controls TCP Small Queue limit per tcp socket.
TCP bulk sender tends to increase packets in flight until it
gets losses notifications. With SNDBUF autotuning, this can
- result in a large amount of packets queued in qdisc/device
- on the local machine, hurting latency of other flows, for
- typical pfifo_fast qdiscs.
- tcp_limit_output_bytes limits the number of bytes on qdisc
- or device to reduce artificial RTT/cwnd and reduce bufferbloat.
