/* WAPF defines the behavior of the Fn+Fx wlan key

 * The significance of values is yet to be found, but

 * most of the time:

 * 0x0 will do nothing

 * 0x1 will allow to control the device with Fn+Fx key.

 * 0x4 will send an ACPI event (0x88) while pressing the Fn+Fx key

 * 0x5 like 0x1 or 0x4

 * So, if something doesn't work as you want, just try other values =)
