		  This setting is only used if the SPI flash pins have been overridden by setting the eFuses

		  When this is the case, the eFuse config only defines 3 of the 4 Quad I/O data pins. The WP pin (aka
		  ESP32 pin "SD_DATA_3" or SPI flash pin "IO2") is not specified in eFuse. The psram only has QPI
		  mode, so a WP pin setting is necessary.

		  If this config item is set to N (default), the correct WP pin will be automatically used for any
		  Espressif chip or module with integrated flash. If a custom setting is needed, set this config item
		  to Y and specify the GPIO number connected to the WP pin.

	  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.)
