99 seconds. max_hw_heartbeat_ms must be set if a driver does not implement
166 max_hw_heartbeat_ms.
197 Drivers implementing max_hw_heartbeat_ms set the hardware watchdog heartbeat
198 to the minimum of timeout and max_hw_heartbeat_ms. Those drivers set the
200 (if it is larger than max_hw_heartbeat_ms), or to the achieved timeout value.
