49 Description: Current state of the transmitter.
50 This file was scheduled to be removed in 2014, but due to its
51 large number of users it will be sticking around for a bit
52 longer. Despite it being marked as stable, the newer "hard" and
53 "soft" interfaces should be preferred, since it is not possible
54 to express the 'soft and hard block' state of the rfkill driver
55 through this interface. There will likely be another attempt to
56 remove it in the future.
57 Values: A numeric value.

59 0: RFKILL_STATE_SOFT_BLOCKED

62 transmitter is (potentially) active
63 2: RFKILL_STATE_HARD_BLOCKED
64 transmitter is forced off by something outside of
65 the driver's control.
