    help
        RT_USING_NETDEV is used in the RT-Thread operating system to enable the Network Device Driver Framework.

        Features:
        Compiles the core code of the network device framework
        Provides a unified interface for operating network devices
        Supports multiple network device types
        Enables related network tools and commands

        Disabled by default; RT_USING_NETDEV is available once enabled.

        help
            NETDEV_USING_IFCONFIG is used to enable or disable the ifconfig command functionality in the system.

            NETDEV_USING_IFCONFIG is enabled by default. When enabled, ifconfig can be used to perform the following functions: 
            View network interface information; 
            Configure network interface parameters.
    config NETDEV_USING_PING
        bool "Enable ping features"
        default y
        help
            NETDEV_USING_PING enables or disables the ping command functionality on the system.

            Function Description:
            Ping is a commonly used network diagnostic tool used to test connectivity between two network devices.

            It is disabled by default; once enabled, the ping function can be used.

    config NETDEV_USING_NETSTAT
        bool "Enable netstat features"
        default y
        help
            NETDEV_USING_NETSTAT enables or disables the netstat command functionality on your system.

            netstat is a command-line tool used to display network connectivity status, routing tables, and network interface statistics.

            It is enabled by default. Once enabled, you can use the netstat command in the shell (FinSH/MSH) to perform the following operations:
            View network connectivity status
            View network interface statistics
            View routing tables
    config NETDEV_USING_AUTO_DEFAULT
        bool "Enable default netdev automatic change features"
        default y
        help
            NETDEV_USING_AUTO_DEFAULT enables or disables automatic switching of the default network interface.

            Enabled by default. When enabled, the system automatically monitors the status of all network interfaces. 
            When a new network interface is enabled and successfully obtains an IP address, the system automatically sets this new interface as the default network interface.
            If the current default network interface becomes disconnected, the system will attempt to select one from other connected network interfaces as the new default interface.
    config NETDEV_USING_LINK_STATUS_CALLBACK
    	bool "Enable netdev callback on link status change"
    	default n
        help
            NETDEV_USING_LINK_STATUS_CALLBACK enables the network link state change callback mechanism.

            It is disabled by default. Once enabled, the netdev framework provides a set of link state change callback registration/deregistration interfaces, 
            allowing users to execute custom business logic when the link state of network devices changes.
                                
    config NETDEV_USING_IPV6
        bool "Enable IPV6 protocol support"
        default n
        help
            NETDEV_USING_IPv6 enables IPv6 protocol stack adaptation.

            Features:
            Adds IPv6 address management to network devices;
            Supports IPv6 link layer adaptation;
            Adapts to the RT-Thread kernel IPv6 protocol stack, providing IPv6 tools such as ping6 and ifconfig6;
            Unifies the operation interface for IPv4/IPv6 devices.

            Disabled by default. Once enabled, the netdev framework expands from "IPv4 only" to "dual-stack (IPv4+IPv6)/pure IPv6" mode.
