            The value of 0 indicates the IP lost timer is disabled, otherwise the timer is enabled.

            The IP address may be lost because of some reasons, e.g. when the station disconnects
            from soft-AP, or when DHCP IP renew fails etc. If the IP lost timer is enabled, it will
            be started everytime the IP is lost. Event SYSTEM_EVENT_STA_LOST_IP will be raised if
            the timer expires. The IP lost timer is stopped if the station get the IP again before
            the timer expires.

            Maximum number of opened File descriptors (FD's) associated with ESP TAP device. ESP TAP FD's take up
            a certain amount of memory, and allowing fewer FD's to be opened at the same time conserves memory.
