(2) Fix: When BBR restarts from idle and if BBR is in PROBE_RTT mode, BBR should check if it's time to exit PROBE_RTT. If yes, then BBR should exit PROBE_RTT mode and restore the cwnd to its full value. (3) Fix: Apply the PROBE_RTT cwnd cap even if the count of fully-ACKed packets is 0. ==================== Signed-off-by: David S. Miller --- 12a7f8696b85aaff3a76cd12a15b101b2af65404
