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.
- Note: For GSO/TSO enabled flows, we try to have at least two
- packets in flight. Reducing tcp_limit_output_bytes might also
- reduce the size of individual GSO packet (64KB being the max)
Default: 131072
tcp_challenge_ack_limit - INTEGER
