+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.
