 676          * that we have allocated SHORT_INQUIRY_LENGTH bytes.  There are
 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

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
