Revision 6065fd0d179b96ddc488c76542349bcb148a95fd authored by Yuchung Cheng on 07 December 2017, 19:33:33 UTC, committed by David S. Miller on 08 December 2017, 19:14:11 UTC
RACK skips an ACK unless it advances the most recently delivered
TX timestamp (rack.mstamp). Since RACK also uses the most recent
RTT to decide if a packet is lost, RACK should still run the
loss detection whenever the most recent RTT changes. For example,
an ACK that does not advance the timestamp but triggers the cwnd
undo due to reordering, would then use the most recent (higher)
RTT measurement to detect further losses.
