     The streams ioctl's don't do much in themselves, except in the sense
that they turn on other behavior by pushing streams modules.  The latter
have more complex behavior.  You could hack I_PUSH of a given name to
enable specific behavior, and then implement that behavior.  The pushed
streams module is responsible for controlling the device (keyboard, mouse,
tablet, and so on), whereas the driver is mostly responsible for
managing the link controller or serial port to which the device is attached.
