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.
