	Already discussed countless times since 96, same answer as
before : not possible.
	For normal devices, you have the full ioctl range, so you can
afford to "waste" this space by coding type/direction in the ioctl
number.
	For networking devices, only a *very* small portion of the
ioctl space goes to the driver (because the various networking
components grab tons of them), so we are required to be more
efficient.
	In summary : if you convert all the regular ifconfig ioctls
(see .../include/linux/sockios.h) to use _IOC() macros and workaround
ioctl space limitation for networking devices, then I'll fix the
wireless ioctls.
