Description: Current state of the transmitter.
This file is deprecated and sheduled to be removed in 2014,
because its not possible to express the 'soft and hard block'
state of the rfkill driver.
Values: A numeric value.
0: RFKILL_STATE_SOFT_BLOCKED
transmitter is turned off by software
1: RFKILL_STATE_UNBLOCKED
transmitter is (potentially) active
2: RFKILL_STATE_HARD_BLOCKED
transmitter is forced off by something outside of
the driver's control.

KernelVersion v2.6.22
Contact: linux-wireless@vger.kernel.org
Description: This file is deprecated because there no longer is a way to
claim just control over a single rfkill instance.
This file is scheduled to be removed in 2012.

a specified type) into a state which also updates the default state for
hotplugged devices.
After an application opens /dev/rfkill, it can read the current state of
all devices, and afterwards can poll the descriptor for hotplug or state
change events.
Applications must ignore operations (the "op" field) they do not handle,
this allows the API to be extended in the future.
Additionally, each rfkill device is registered in sysfs and there has the
following attributes:
name: Name assigned by driver to this key (interface or driver name).
type: Driver type string ("wlan", "bluetooth", etc).
persistent: Whether the soft blocked state is initialised from
non-volatile storage at startup.
state: Current state of the transmitter

After an application opens /dev/rfkill, it can read the current state of all
