| 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 two, |
| all interfaces (WiFi station, WiFi softap) receive a universally administered MAC |
| address. |
| They are generated sequentially by adding 0, and 1 (respectively) to the final octet of |
| the base MAC address. If the number of universal MAC addresses is one, only WiFi station |
| receives a universally administered MAC address. |
| The WiFi softap receives local MAC addresses. It's derived from the universal WiFi |
| station MAC addresses. |
| 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 1 or 2 per device). |
