Subject: [PATCH 0/2 net] revert a F-RTO extension due to broken middle-boxes

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.

Yuchung Cheng (2):
  tcp: revert F-RTO middle-box workaround
  tcp: revert F-RTO extension to detect more spurious timeouts
