DKconfig.mac13 all four interfaces (WiFi station, WiFi softap, Bluetooth and Ethernet) receive a universally
14 administered MAC address. These are generated sequentially by adding 0, 1, 2 and 3 (respectively)
16 only two interfaces (WiFi station and Bluetooth) receive a universally administered MAC address.
17 These are generated sequentially by adding 0 and 1 (respectively) to the base MAC address.
18 The remaining two interfaces (WiFi softap and Ethernet) receive local MAC addresses.
19 These are derived from the universal WiFi station and Bluetooth MAC addresses, respectively.
