+   v4l-ioctl-test - This small utility sends dumb v4l2 ioctl to a device.
+   It is meant to check ioctl debug messages generated and to check
+	if a function is implemented by that device.
+   flag INTERNAL will send v4l internal messages, defined at v4l2-common.h
+	and v4l_decoder.h. These messages shouldn't be handled by video
+   driver itself, but for internal video and/or audio decoders.
