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).
