Subject: [PATCH net-next 00/14] tcp: BBR congestion control algorithm

tcp: BBR congestion control algorithm

This patch series implements a new TCP congestion control algorithm:
BBR (Bottleneck Bandwidth and RTT). A paper with a detailed
description of BBR will be published in ACM Queue, September-October
2016, as "BBR: Congestion-Based Congestion Control". BBR is widely
deployed in production at Google.

The patch series starts with a set of supporting infrastructure
changes, including a few that extend the congestion control
framework. The last patch adds BBR as a TCP congestion control
module. Please see individual patches for the details.

Eric Dumazet (1):
  net_sched: sch_fq: add low_rate_threshold parameter

Neal Cardwell (8):
  lib/win_minmax: windowed min or max estimator
  tcp: use windowed min filter library for TCP min_rtt estimation
  tcp: count packets marked lost for a TCP connection
  tcp: allow congestion control module to request TSO skb segment count
  tcp: export tcp_tso_autosize() and parameterize minimum number of TSO
    segments
  tcp: export tcp_mss_to_mtu() for congestion control modules
  tcp: increase ICSK_CA_PRIV_SIZE from 64 bytes to 88
  tcp_bbr: add BBR congestion control

Soheil Hassas Yeganeh (1):
  tcp: track application-limited rate samples

Yuchung Cheng (4):
  tcp: track data delivery rate for a TCP connection
  tcp: export data delivery rate
  tcp: allow congestion control to expand send buffer differently
  tcp: new CC hook to set sending rate with rate_sample in any CA state
