Description:	(RW) On the front panel of the Turris Omnia router there is also

		a button which can be used to control the intensity of all the

		LEDs at once, so that if they are too bright, user can dim them.



		The microcontroller cycles between 8 levels of this global

		brightness (from 100% to 0%), but this setting can have any

		integer value between 0 and 100. It is therefore convenient to be

		able to change this setting from software.
