These are the ioctls for the special-purpose misc device /dev/nosy, the
interface to the IEEE 1394 packet sniffer/ protocol analyzer driver.
Currently only the numbers 00...02 are in use; let's block a few more
for unforeseen use cases.

As mentioned in patch 1/2, this is up for discussion. These ioctls have
been used during nosy's out-of-tree life for several years; but due to
the nature of this driver and its frontend as special-purpose
application on special hardware, an incompatible change of these ioctls
in the process of mainline merge won't be overly hurtful.
