EXPERIMENTAL: UWB
-----------------
This feature is marked EXPERIMENTAL because it has not been extensively
tested and validated in various ThinkPad models yet. The feature may not
work as expected. USE WITH CAUTION! To use this feature, you need to supply
the experimental=1 parameter when loading the module.
sysfs rfkill class: switch "tpacpi_uwb_sw"
This feature exports an rfkill controller for the UWB device, if one is
present and enabled in the BIOS.
