Feature request: assemble ioctl number from raw parameters

[gschwaer]

Hi,

I have a small feature request: It would be helpful if one could specify the ioctl in it's raw (unencoded) form, i.e., like ./ioctl /dev/mydev dir=2,type=1,nr=0,size=4. This tool then just has to assemble it using the macro _IOC from ioctl.h:

#define _IOC(dir,type,nr,size) \
	(((dir)  << _IOC_DIRSHIFT) | \
	 ((type) << _IOC_TYPESHIFT) | \
	 ((nr)   << _IOC_NRSHIFT) | \
	 ((size) << _IOC_SIZESHIFT))
