 667          * that we have allocated SHORT_INQUIRY_LENGTH bytes.  There are
 668          * two reasons for this:
 669          *
 670          *  - The SCSI spec says that when a length field is only 1 byte,
 671          *    a value of 0 will be interpreted as 256.  Therefore
 672          *    scsi_inquiry() will convert an inq_len (which is passed in as
 673          *    a u_int32_t, but the field in the CDB is only 1 byte) of 256
 674          *    to 0.  Evidently, very few devices meet the spec in that
 675          *    regard.  Some devices, like many Seagate disks, take the 0 as
 676          *    0, and don't return any data.  One Pioneer DVD-R drive
 677          *    returns more data than the command asked for.
 678          *
 679          *    So, since there are numerous devices that just don't work
 680          *    right with the full inquiry size, we don't send the full size.
 681          *
 682          *  - The second reason not to use the full inquiry data length is
 683          *    that we don't need it here.  The only reason we issue a
 684          *    standard inquiry is to get the vendor name, device name,
 685          *    and revision so scsi_print_inquiry() can print them.
 686          *
 687          * If, at some point in the future, more inquiry data is needed for
 688          * some reason, this code should use a procedure similar to the
 689          * probe code.  i.e., issue a short inquiry, and determine from
 690          * the additional length passed back from the device how much
 691          * inquiry data the device supports.  Once the amount the device
 692          * supports is determined, issue an inquiry for that amount and no

3559          * This is a gross hack.  There really aren't many other good
3560          * options (excuse the pun) for parsing options in a situation like
3561          * this.  getopt is kinda braindead, so you end up having to run
3562          * through the options twice, and give each invocation of getopt
3563          * the option string for the other invocation.
3564          *
3565          * You would think that you could just have two groups of options.
3566          * The first group would get parsed by the first invocation of
3567          * getopt, and the second group would get parsed by the second
3568          * invocation of getopt.  It doesn't quite work out that way.  When
3569          * the first invocation of getopt finishes, it leaves optind pointing
3570          * to the argument _after_ the first argument in the second group.
3571          * So when the second invocation of getopt comes around, it doesn't
3572          * recognize the first argument it gets and then bails out.
3573          *
3574          * A nice alternative would be to have a flag for getopt that says
3575          * "just keep parsing arguments even when you encounter an unknown
3576          * argument", but there isn't one.  So there's no real clean way to
3577          * easily parse two sets of arguments without having one invocation
3578          * of getopt know about the other.
3579          *
3580          * Without this hack, the first invocation of getopt would work as
3581          * long as the generic arguments are first, but the second invocation
3582          * (in the subfunction) would fail in one of two ways.  In the case
3583          * where you don't set optreset, it would fail because optind may be
3584          * pointing to the argument after the one it should be pointing at.
3585          * In the case where you do set optreset, and reset optind, it would
3586          * fail because getopt would run into the first set of options, which
3587          * it doesn't understand.
3588          *
3589          * All of this would "sort of" work if you could somehow figure out
3590          * whether optind had been incremented one option too far.  The
3591          * mechanics of that, however, are more daunting than just giving
3592          * both invocations all of the expect options for either invocation.
3593          *
3594          * Needless to say, I wouldn't mind if someone invented a better
3595          * (non-GPL!) command line parsing interface than getopt.  I
3596          * wouldn't mind if someone added more knobs to getopt to make it
3597          * work better.  Who knows, I may talk myself into doing it someday,
