This looks strange. Driver dell_rbnt is just receiver of BIOS/ACPI events. It receive hotkey or slide switch event and translate it into either linux input keypress or rfkill block event. But dell_rbnt driver itself cannot set or change wireless rfkill or airplane mode. So my opinion is that BIOS/ACPI could send such event, dell_rbnt then propagate it into userspace and some application process it and do something... --=20 Pali Roh=C3=A1r pali.rohar@gmail.com
