677 	 * two reasons for this:
678 	 *
679 	 *  - The SCSI spec says that when a length field is only 1 byte,
680 	 *    a value of 0 will be interpreted as 256.  Therefore
681 	 *    scsi_inquiry() will convert an inq_len (which is passed in as
682 	 *    a u_int32_t, but the field in the CDB is only 1 byte) of 256
683 	 *    to 0.  Evidently, very few devices meet the spec in that
684 	 *    regard.  Some devices, like many Seagate disks, take the 0 as
685 	 *    0, and don't return any data.  One Pioneer DVD-R drive
686 	 *    returns more data than the command asked for.
687 	 *
688 	 *    So, since there are numerous devices that just don't work
689 	 *    right with the full inquiry size, we don't send the full size.
690 	 *
691 	 *  - The second reason not to use the full inquiry data length is
692 	 *    that we don't need it here.  The only reason we issue a
693 	 *    standard inquiry is to get the vendor name, device name,
694 	 *    and revision so scsi_print_inquiry() can print them.
695 	 *
696 	 * If, at some point in the future, more inquiry data is needed for
697 	 * some reason, this code should use a procedure similar to the
698 	 * probe code.  i.e., issue a short inquiry, and determine from
699 	 * the additional length passed back from the device how much
700 	 * inquiry data the device supports.  Once the amount the device
701 	 * supports is determined, issue an inquiry for that amount and no
702 	 * more.

3569 	 * Ahh, getopt(3) is a pain.
3570 	 *
3571 	 * This is a gross hack.  There really aren't many other good
3572 	 * options (excuse the pun) for parsing options in a situation like
3573 	 * this.  getopt is kinda braindead, so you end up having to run
3574 	 * through the options twice, and give each invocation of getopt
3575 	 * the option string for the other invocation.
3576 	 *
3577 	 * You would think that you could just have two groups of options.
3578 	 * The first group would get parsed by the first invocation of
3579 	 * getopt, and the second group would get parsed by the second
3580 	 * invocation of getopt.  It doesn't quite work out that way.  When
3581 	 * the first invocation of getopt finishes, it leaves optind pointing
3582 	 * to the argument _after_ the first argument in the second group.
3583 	 * So when the second invocation of getopt comes around, it doesn't
3584 	 * recognize the first argument it gets and then bails out.
3585 	 *
3586 	 * A nice alternative would be to have a flag for getopt that says
3587 	 * "just keep parsing arguments even when you encounter an unknown
3588 	 * argument", but there isn't one.  So there's no real clean way to
3589 	 * easily parse two sets of arguments without having one invocation
3590 	 * of getopt know about the other.
3591 	 *
3592 	 * Without this hack, the first invocation of getopt would work as
3593 	 * long as the generic arguments are first, but the second invocation
3594 	 * (in the subfunction) would fail in one of two ways.  In the case
3595 	 * where you don't set optreset, it would fail because optind may be
3596 	 * pointing to the argument after the one it should be pointing at.
3597 	 * In the case where you do set optreset, and reset optind, it would
3598 	 * fail because getopt would run into the first set of options, which
3599 	 * it doesn't understand.
3600 	 *
3601 	 * All of this would "sort of" work if you could somehow figure out
3602 	 * whether optind had been incremented one option too far.  The
3603 	 * mechanics of that, however, are more daunting than just giving
3604 	 * both invocations all of the expect options for either invocation.
3605 	 *
3606 	 * Needless to say, I wouldn't mind if someone invented a better
3607 	 * (non-GPL!) command line parsing interface than getopt.  I
3608 	 * wouldn't mind if someone added more knobs to getopt to make it
3609 	 * work better.  Who knows, I may talk myself into doing it someday,
3610 	 * if the standards weenies let me.  As it is, it just leads to
3611 	 * hackery like this and causes people to avoid it in some cases.
