	  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).
