  42 * Normally, the ioctl determines the logical unit for this command by
  43 * the major,minor number of the fd passed to ioctl.  If you need to send
  44 * a command to a different/nonexistant unit (such as during config), you
  45 * can override the normal behavior by setting the unit valid bit. (Normally,
  46 * it should be zero) The controller the command is sent to is still
  47 * determined by the major number of the open device.
