| 10 | Configure the number of universally administered (by IEEE) MAC addresses. |
| 11 | During initialization, MAC addresses for each network interface are generated or derived from a |
| 12 | single base MAC address. |
| 13 | If the number of universal MAC addresses is four, all four interfaces (WiFi station, WiFi softap, |
| 14 | Bluetooth and Ethernet) receive a universally administered MAC address. These are generated |
| 15 | sequentially by adding 0, 1, 2 and 3 (respectively) to the final octet of the base MAC address. |
| 16 | If the number of universal MAC addresses is two, only two interfaces (WiFi station and Bluetooth) |
| 17 | receive a universally administered MAC address. These are generated sequentially by adding 0 |
| 18 | and 1 (respectively) to the base MAC address. The remaining two interfaces (WiFi softap and Ethernet) |
| 19 | receive local MAC addresses. These are derived from the universal WiFi station and Bluetooth MAC |
| 20 | addresses, respectively. |
| 21 | When using the default (Espressif-assigned) base MAC address, either setting can be used. When using |
| 22 | a custom universal MAC address range, the correct setting will depend on the allocation of MAC |
| 23 | addresses in this range (either 2 or 4 per device.) |
| 24 | Note that ESP32-C3 has no integrated Ethernet MAC. Although it's possible to use the esp_read_mac() |
| 25 | API to return a MAC for Ethernet, this can only be used with an external MAC peripheral. |
