 16Description:	(RO) Contains device first MAC address. Each Turris Omnia is
 17		allocated 3 MAC addresses. The two additional addresses are
 18		computed from the first one by incrementing it.

 29Description:	(RW) The front button on the Turris Omnia router can be
 30		configured either to change the intensity of all the LEDs on the
 31		front panel, or to send the press event to the CPU as an
 32		interrupt.
 33
 34		This file switches between these two modes:
 35		 - ``mcu`` makes the button press event be handled by the MCU to
 36		   change the LEDs panel intensity.
 37		 - ``cpu`` makes the button press event be handled by the CPU.

 45Description:	(RW) Newer versions of the microcontroller firmware of the
 46		Turris Omnia router support powering off the router into true
 47		low power mode. The router can be powered on by pressing the
 48		front button.
 49
