| 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.) |
