 * Normally, the ioctl determines the logical unit for this command by

 * the major,minor number of the fd passed to ioctl.  If you need to send

 * a command to a different/nonexistant unit (such as during config), you

 * can override the normal behavior by setting the unit valid bit. (Normally,

 * it should be zero) The controller to which the command is sent is still

 * determined by the major number of the open device.
