Subject: [PATCH 0/2 net] revert a F-RTO extension due to broken middle-boxes
Date: Tue, 27 Feb 2018 14:15:00 -0800 [thread overview]
Message-ID: <20180227221502.3294-1-ycheng@google.com> (raw)
This patch series reverts a (non-standard) TCP F-RTO extension that aimed
to detect more spurious timeouts. Unfortunately it could result in poor
performance due to broken middle-boxes that modify TCP packets. E.g.
https://www.spinics.net/lists/netdev/msg484154.html
We believe the best and simplest solution is to just revert the change.
