    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"
        range 1 64
        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. The valid value is from 1
            to 64.

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

    choice MDNS_TASK_AFFINITY
        prompt "mDNS task affinity"
        default MDNS_TASK_AFFINITY_CPU0
        help
            Allows setting mDNS tasks affinity, i.e. whether the task is pinned to
            CPU0, pinned to CPU1, or allowed to run on any CPU.

        config MDNS_TASK_AFFINITY_NO_AFFINITY
            bool "No affinity"

        int "mDNS adding service timeout (ms)"
        range 10 30000
        default 2000
        help
            Configures timeout for adding a new mDNS service. Adding a service
            fails if could not be completed within this time.

    config MDNS_STRICT_MODE
        bool "mDNS strict mode"
        default "n"
        help
            Configures strict mode. Set this to 1 for the mDNS library to strictly follow the RFC6762:
            Currently the only strict feature: Do not repeat original questions in response packets
            (defined in RFC6762 sec. 6).
            Default configuration is 0, i.e. non-strict mode, since some implementations,
            such as lwIP mDNS resolver (used by standard POSIX API like getaddrinfo, gethostbyname)
            could not correctly resolve advertised names.

    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_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.
