1 Rfkill is a small userspace tool to query the state of the rfkill switches,
2 buttons and subsystem interfaces.
3 Some devices come with a hard switch that lets you kill different types of
4 RF radios: 802.11, Bluetooth, NFC, UWB, WAN, WIMAX, FM.
5 Some times these buttons may kill more than one RF type.
6 The Linux kernel rfkill subsystem exposes these hardware buttons and lets
7 userspace query its status and set its status through a /dev/rfkill.
8 Given that at times some RF devices do not have hardware rfkill buttons
9 rfkill the Linux kernel also exposes software rfkill capabilities that
10 allows userspace to mimic a hardware rfkill event and turn on or off RF.
