    config MDNS_MAX_INTERFACES
        int "Max number of interfaces"
        range 1 9
        default 3
        help
            Number of network interfaces to be served by the mDNS library.
            Lowering this number helps to reduce some static RAM usage.

    config MDNS_MAX_SERVICES
        int "Max number of services"
        default 10
        help
            Services take up a certain amount of memory, and allowing fewer
            services to be open at the same time conserves memory. Specify
            the maximum amount of services here.

    config MDNS_TASK_PRIORITY
        int "mDNS task priority"
        range 1 255
        default 1
        help
            Allows setting mDNS task priority. Please do not set the task priority
            higher than priorities of system tasks. Compile time warning/error
            would be emitted if the chosen task priority were too high.

    config MDNS_ACTION_QUEUE_LEN
        int "Maximum actions pending to the server"
        range 8 64
        default 16
        help
            Allows setting the length of mDNS action queue.

    config MDNS_TASK_STACK_SIZE
        int "mDNS task stack size"
        default 4096
        help
            Allows setting mDNS task stacksize.

            Allows setting mDNS tasks affinity, i.e. whether the task is pinned to
            CPU0, pinned to CPU1, or allowed to run on any CPU.

        help
            Configures timeout for adding a new mDNS service. Adding a service
            fails if could not be completed within this time.

    config MDNS_TIMER_PERIOD_MS
        int "mDNS timer period (ms)"
        range 10 10000
        default 100
        help
            Configures period of mDNS timer, which periodically transmits packets
            and schedules mDNS searches.

    config MDNS_NETWORKING_SOCKET
        bool "Use BSD sockets for mDNS networking"
        default n
        help
            Enables optional mDNS networking implementation using BSD sockets
            in UDP multicast mode.
            This option creates a new thread to serve receiving packets (TODO).
            This option uses additional N sockets, where N is number of interfaces.

    config MDNS_SKIP_SUPPRESSING_OWN_QUERIES
        bool "Skip suppressing our own packets"
        default n
        help
            Enable only if the querier and the responder share the same IP address.
            This usually happens in test mode, where we may run multiple instances of
            responders/queriers on the same interface.

    config MDNS_ENABLE_DEBUG_PRINTS
        bool "Enable debug prints of mDNS packets"
        default n

            Enable for the library to log received and sent mDNS packets to stdout.

    config MDNS_RESPOND_REVERSE_QUERIES
        bool "Enable responding to IPv4 reverse queries"
        default n
        help
            Enables support for IPv4 reverse lookup. If enabled, the mDNS library
            response to PTR queries of "A.B.C.D.in-addr.arpa" type.

    config MDNS_MULTIPLE_INSTANCE
        bool "Multiple instances under the same service type"
        default y
        help
            Enables adding multiple service instances under the same service type.

                Set up mDNS for the default WiFi station.
                Disable this option if you do not need mDNS on default WiFi STA.

                Set up mDNS for the default WiFi Access Point.
                Disable this option if you do not need mDNS on default WiFi AP.
