Subject: [PATCH net 0/3] TCP BBR sampling fixes for loss recovery undo

This patch series has a few minor bug fixes for cases where spurious
loss recoveries can trick BBR estimators into estimating that the
available bandwidth is much lower than the true available bandwidth.
In both cases the fix here is to just reset the estimator upon loss
recovery undo.

Neal Cardwell (3):
  tcp_bbr: record "full bw reached" decision in new full_bw_reached bit
  tcp_bbr: reset full pipe detection on loss recovery undo
  tcp_bbr: reset long-term bandwidth sampling on loss recovery undo
