Recoveries in a bidirectional flows suffer quite badly because of this, both NewReno and SACK are affected. After this patch, rate halving is performed for ACK only if packets in flight was supposedly changed too. Signed-off-by: Ilpo Järvinen Signed-off-by: David S. Miller --- Reading git-diff-tree failed
