0003 For details to this subsystem look at Documentation/driver-api/rfkill.rst.

0005 For the deprecated ``/sys/class/rfkill/*/claim`` knobs of this interface look in
0006 Documentation/ABI/removed/sysfs-class-rfkill.

0012 Description: The rfkill class subsystem folder.
0013 Each registered rfkill driver is represented by an rfkillX
0014 subfolder (X being an integer >= 0).

0049 Description: Current state of the transmitter.
0050 This file was scheduled to be removed in 2014, but due to its
0051 large number of users it will be sticking around for a bit
0052 longer. Despite it being marked as stable, the newer "hard" and
0053 "soft" interfaces should be preferred, since it is not possible
0054 to express the 'soft and hard block' state of the rfkill driver
0055 through this interface. There will likely be another attempt to
0056 remove it in the future.
0057 Values: A numeric value.
0058
0059 0: RFKILL_STATE_SOFT_BLOCKED
0060 transmitter is turned off by software
0061 1: RFKILL_STATE_UNBLOCKED
0062 transmitter is (potentially) active
0063 2: RFKILL_STATE_HARD_BLOCKED
0064 transmitter is forced off by something outside of
0065 the driver's control.
