Notification with VPC2 bit 5 set is generated when the wireless hotkey is pressed. BIOS fires this to notify a Windows application to handle the RF switch.
On Linux, there is no such application. This patch implements a toggle for all RF devices through accessing the EC I/O ports. Without the explicit EC commands, the wifi LED is always on.
