[net-next,0/2] more accurate DSACK processing for RACK-TLP

Message

Neal Cardwell July 27, 2021, 2:42 p.m. UTC

This patch series includes two minor improvements to tighten up the accuracy of
the processing of incoming DSACK information, so that RACK-TLP behavior is
faster and more precise: first, to ensure we detect packet loss in some extra
corner cases; and second, to avoid growing the RACK reordering window (and
delaying fast recovery) in cases where it seems clear we don't need to.
