49Description: 	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.
57Values: 	A numeric value.
58
59		0: RFKILL_STATE_SOFT_BLOCKED
60			transmitter is turned off by software
61		1: RFKILL_STATE_UNBLOCKED
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.
