choice ESP32S3_UNIVERSAL_MAC_ADDRESSES bool "Number of universally administered (by IEEE) MAC address" default ESP32S3_UNIVERSAL_MAC_ADDRESSES_FOUR help 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 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.) config ESP32S3_UNIVERSAL_MAC_ADDRESSES_TWO bool "Two" select ESP_MAC_ADDR_UNIVERSE_WIFI_STA select ESP_MAC_ADDR_UNIVERSE_BT config ESP32S3_UNIVERSAL_MAC_ADDRESSES_FOUR bool "Four" select ESP_MAC_ADDR_UNIVERSE_WIFI_STA select ESP_MAC_ADDR_UNIVERSE_WIFI_AP select ESP_MAC_ADDR_UNIVERSE_BT select ESP_MAC_ADDR_UNIVERSE_ETH endchoice config ESP32S3_UNIVERSAL_MAC_ADDRESSES int default 2 if ESP32S3_UNIVERSAL_MAC_ADDRESSES_TWO default 4 if ESP32S3_UNIVERSAL_MAC_ADDRESSES_FOUR
