3.13.11.11 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Per Hurtig <[email protected]> [ Upstream commit bef1909ee3ed1ca39231b260a8d3b4544ecd0c8f ] Fix to a problem observed when losing a FIN segment that does not contain data. In such situations, TLP is unable to recover from *any* tail loss and instead adds at least PTO ms to the retransmission process, i.e., RTO = RTO + PTO.
