Defines the default maximum retransmission timeout value (RTO). The calculated RTO for all TCP connections cannot exceed this value. See also tcp_ip_abort_interval.

Do not change the value in a normal network environment.
If, in some special circumstances, the round-trip time (RTT) for a connection is about 10 seconds, you can increase this value. If you change this value, you should also change the tcp_ip_abort_interval parameter. Change the value of tcp_ip_abort_interval to at least four times the value of tcp_rexmit_interval_max.
