Subject: [PATCH net-next 0/3] tcp: fixes some congestion control corner cases

This patch series fixes corner cases of TCP congestion control.
First issue is to avoid continuing slow start when cwnd reaches ssthresh.
Second issue is incorrectly processing order of congestion state and
cwnd update when entering fast recovery or undoing cwnd.

Yuchung Cheng (3):
  tcp: add tcp_in_slow_start helper
  tcp: do not slow start when cwnd equals ssthresh
  tcp: update congestion state first before raising cwnd
