F-RTO is an enhanced recovery algorithm for TCP retransmission
timeouts. It is particularly beneficial in wireless environments
where packet loss is typically due to random radio interference

the peer, but in a typical case, however, where wireless link is
the local access link and most of the data flows downlink, the

If set to 1, basic version is enabled. 2 enables SACK enhanced
F-RTO if flow uses SACK. The basic version can be used also when

interacts badly with the packet counting of the SACK enabled TCP
flow.
