[tcp keepalive options]
Are options that configure how TCP keep-alive probes are sent. The keep-
alive options (“idle,” “probe_count,” “probe_interval”) should be

keepalive={on|off},” or clients such as autoconnect (“set autoconnect
keepalive={on|off}”).

The amount of time, in seconds, to wait while not receiving TCP
packets before sending out a keep-alive probe.
probe_count=5-30
The number of TCP keep-alive probes (specially formatted TCP
frames) to send out before closing the TCP connection.
probe_interval=10-75
The amount of time, in seconds, to wait between sending TCP keep-
alive probes.
