According to https:/ /github. com/torvalds/ linux/blob/ master/ drivers/ platform/ x86/dell- wmi.c this key isn't supported by kernel. keymap_ type_0010. Right now it exists only in dell_wmi_ keymap_ type_0000.
To add support record { KE_IGNORE, 0xe008, { KEY_RFKILL } } must be added to array dell_wmi_
