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 ).
