Is there any meaning in the way ioctl numbers are selected? There seem
to be several ioctl numbers which have different and totally unrelated
meanings for different devices. If I want to add an ioctl to a driver,
can I just pick any number which is not currently meaningful to that
driver?
Specifically, will anybody mind if I define and implement the
following ioctls, as documented in tun(4):
#define TUNSIFMODE _IOW('t', 93, int) /* set ptp/bcast mode */
#define TUNSLMODE _IOW('t', 94, int) /* set link layer mode */
