I wish to suggest to developers to add this new knob : tcp_retries2_time - INTEGER This value influences the timeout (seconds) of an alive TCP connection, when RTO retransmissions remain unacknowledged. RFC 1122 recommends at least 100 seconds for the timeout, which corresponds to a value of at least 8. Rationale : * I see too many abuse of tcp_retries2, because even if you check the RTO, it will change with different connections, routing, etc. * It will be friendly and I think better to document an absolute value. See other parameters with two knobs ( example : dirty_ratio, dirty_ratio_bytes ).
