*Number of universally administered (by IEEE) MAC address*

Type: ``bool``

    Configure the number of universally administered (by IEEE) MAC addresses.
    During initialization, MAC addresses for each network interface are generated or
    derived from a single base MAC address. If the number of universal MAC addresses is two,
    all interfaces (WiFi station, WiFi softap) receive a universally administered MAC
    address.
    They are generated sequentially by adding 0, and 1 (respectively) to the final octet of
    the base MAC address. If the number of universal MAC addresses is one, only WiFi station
    receives a universally administered MAC address.
    The WiFi softap receives local MAC addresses. It's derived from the universal WiFi
    station MAC addresses.
    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 1 or 2 per device).
