490tcp_thin_linear_timeouts - BOOLEAN
491 Enable dynamic triggering of linear timeouts for thin streams.
492 If set, a check is performed upon retransmission by timeout to
493 determine if the stream is thin (less than 4 packets in flight).
494 As long as the stream is found to be thin, up to 6 linear
495 timeouts may be performed before exponential backoff mode is
496 initiated. This improves retransmission latency for
497 non-aggressive thin streams, often found to be time-dependent.
498 For more information on thin streams, see
