menuconfig KCONFIG_USEMODULE_GNRC_NETIF
    bool "Configure GNRC network interface"
    depends on USEMODULE_GNRC_NETIF
    help
        Configure GNRC network interface using Kconfig.

config GNRC_NETIF_MSG_QUEUE_SIZE_EXP
    int "Exponent for the message queue size for network interface threads (as 2^n)"
    default 4
    help
        As the queue size ALWAYS needs to be power of two, this option
        represents the exponent of 2^n, which will be used as the size of
        the queue.

config GNRC_NETIF_IPV6_ADDRS_NUMOF
    int "Maximum number of unicast and anycast addresses per interface"
    default 3 if DHCPV6_CLIENT_ADDR_LEASE_MAX != 0
    default 2
    help
        If you change this, please make sure that
        @ref CONFIG_GNRC_NETIF_IPV6_GROUPS_NUMOF is also large enough to fit the
        addresses' solicited nodes multicast addresses.
        Default: 2 (1 link-local + 1 global address).

config GNRC_NETIF_DEFAULT_HL
    int "Default hop limit"
    default 64

config GNRC_NETIF_MIN_WAIT_AFTER_SEND_US
    int "Minimum wait time after a send operation"
    default 0
    help
        This value is expressed in microseconds. It is purely meant as a debugging
        feature to slow down a radios sending.

config GNRC_NETIF_NONSTANDARD_6LO_MTU
    bool "Enable usage of non standard MTU for 6LoWPAN network interfaces"
    depends on USEMODULE_GNRC_NETIF_6LO
    help
        Enables the usage of non standard MTU for 6LoWPAN network interfaces.
        This is non compliant with RFC 4944 and RFC 7668 and might not be
        supported by other implementations.

config GNRC_NETIF_LORAWAN_NETIF_HDR
    bool "Encode LoRaWAN port in GNRC netif header"
    depends on USEMODULE_GNRC_LORAWAN
    help
        When set, GNRC Netif will interpret
        the destination address of the GNRC netif header as
        the LoRaWAN port. For downlinks, a GNRC netif header
        with the received port in destination field will be
        included in the first snip. From Release 2021.10 all
        GNRC LoRaWAN packets will include the GNRC Netif
        header. Therefore this parameter will be removed

config GNRC_NETIF_IPV6_BR_AUTO_6CTX
    bool "Automatically add 6LoWPAN compression at border router"
    default y
    depends on USEMODULE_GNRC_IPV6_NIB_6LBR && USEMODULE_GNRC_SIXLOWPAN_IPHC && USEMODULE_GNRC_SIXLOWPAN_CTX
    help
        When set, 6LoWPAN compression context 0 will be automatically set for the prefix configured
        by prefix deligation at the border router.
