choice ESP32P4_UNIVERSAL_MAC_ADDRESSES bool "Number of universally administered (by IEEE) MAC address" default ESP32P4_UNIVERSAL_MAC_ADDRESSES_ONE 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 one, only Ethernet interface receives a universally administered MAC address. It's generated by adding 0 to the base MAC address. 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. config ESP32P4_UNIVERSAL_MAC_ADDRESSES_ONE bool "One" select ESP_MAC_UNIVERSAL_MAC_ADDRESSES_ONE select ESP_MAC_ADDR_UNIVERSE_ETH endchoice config ESP32P4_UNIVERSAL_MAC_ADDRESSES int default 1 if ESP32P4_UNIVERSAL_MAC_ADDRESSES_ONE
