[PATCH net-next] tcp: use RFC6298 compliant TCP RTO calculation

2016-06-13 Thread Daniel Metz
This patch adjusts Linux RTO calculation to be RFC6298 Standard compliant. MinRTO is no longer added to the computed RTO, RTO damping and overestimation are decreased. In RFC 6298 Standard TCP Retransmission Timeout (RTO) calculation the calculated RTO is rounded up to the Minimum RTO (MinRTO), if
