        Configure the number of universally administered (by IEEE) MAC addresses.
        During initialisation, MAC addresses for each network interface are generated or derived from a 
        single base MAC address.
        If the number of universal MAC addresses is four, all four interfaces (WiFi station, WiFi softap, 
        Bluetooth and Ethernet) receive a universally administered MAC address. These are generated 
        sequentially by adding 0, 1, 2 and 3 (respectively) to the final octet of the base MAC address.
        If the number of universal MAC addresses is two, only two interfaces (WiFi station and Bluetooth) 
        receive a universally administered MAC address. These are generated sequentially by adding 0 
        and 1 (respectively) to the base MAC address. The remaining two interfaces (WiFi softap and Ethernet) 
        receive local MAC addresses. These are derived from the universal WiFi station and Bluetooth MAC 
        addresses, respectively.
        When using the default (Espressif-assigned) base MAC address, either setting can be used. When using 
        a custom universal MAC address range, the correct setting will depend on the allocation of MAC 
        addresses in this range (either 2 or 4 per device.)

    default y
    help
        Most people are used to end their printf strings with a newline. If this
        is sent as is to the serial port, most terminal programs will only move the
        cursor one line down, not also move it to the beginning of the line. This
        is usually done by an added CR character. Enabling this will make the
        standard output code automatically add a CR character before a LF.
        
        With this option enabled, C standard library functions which read from UART 
        (like scanf) will convert "\r\n" character sequences back to "\n".

        of functions. These functions have been compiled with so-called "nano"
        formatting option. This option doesn't support 64-bit integer formats and C99
        features, such as positional arguments.

        For more details about "nano" formatting option, please see newlib readme file,
        search for '--enable-newlib-nano-formatted-io':
        https://sourceware.org/newlib/README

        If this option is enabled, build system will use functions available in
        ROM, reducing the application binary size. Functions available in ROM run
        faster than functions which run from flash. Functions available in ROM can
        also run when flash instruction cache is disabled.

        Set the number of WiFi static rx buffers. Each buffer takes approximately 1.6KB of RAM.
        The static rx buffers are allocated when esp_wifi_init is called, they are not freed
        until esp_wifi_deinit is called. 
        WiFi hardware use these buffers to receive packets, generally larger number for higher
        throughput but more memory, smaller number for lower throughput but less memory.

        Set the number of WiFi dynamic rx buffers, 0 means no limitation for dynamic rx buffer
        allocation. The size of dynamic rx buffers is not fixed.
        For each received packet in static rx buffers, WiFi driver makes a copy
        to dynamic rx buffers and then deliver it to high layer stack. The dynamic rx buffer
        is freed when the application, such as socket, successfully received the packet.
        For some applications, the WiFi driver receiving speed is faster than application 
        consuming speed, we may run out of memory if no limitation for the dynamic rx buffer
        number.  Generally the number of dynamic rx buffer should be no less than static
        rx buffer number if it is not 0.

        Select type of WiFi tx buffers and show the submenu with the number of WiFi tx buffers choice. 
        If "STATIC" is selected, WiFi tx buffers are allocated when WiFi is initialized and released
        when WiFi is de-initialized. If "DYNAMIC" is selected, WiFi tx buffer is allocated when tx
        data is delivered from LWIP to WiFi and released when tx data is sent out by WiFi.
        The size of each static tx buffers is fixed to about 1.6KB and the size of dynamic tx buffers is 
        depend on the length of the data delivered from LWIP.
        If PSRAM is enabled, "STATIC" should be selected to guarantee enough WiFi tx buffers. 
        If PSRAM is disabled, "DYNAMIC" should be selected to improve the utilization of RAM.
