         If the number of universal MAC addresses is one, only Ethernet interface receives a universally

 In ESP-IDF, the MAC addresses for the various network interfaces are calculated from a single **base MAC address**. By default, the Espressif base MAC address is used. This base MAC address is pre-programmed into the {IDF_TARGET_NAME} eFuse in the factory during production.
