 702          * that we have allocated SHORT_INQUIRY_LENGTH bytes.  There are
 703          * two reasons for this:
 704          *
 705          *  - The SCSI spec says that when a length field is only 1 byte,
 706          *    a value of 0 will be interpreted as 256.  Therefore
 707          *    scsi_inquiry() will convert an inq_len (which is passed in as
 708          *    a u_int32_t, but the field in the CDB is only 1 byte) of 256
 709          *    to 0.  Evidently, very few devices meet the spec in that
 710          *    regard.  Some devices, like many Seagate disks, take the 0 as
 711          *    0, and don't return any data.  One Pioneer DVD-R drive
 712          *    returns more data than the command asked for.
 713          *
 714          *    So, since there are numerous devices that just don't work
 715          *    right with the full inquiry size, we don't send the full size.
 716          *
 717          *  - The second reason not to use the full inquiry data length is
 718          *    that we don't need it here.  The only reason we issue a
 719          *    standard inquiry is to get the vendor name, device name,
 720          *    and revision so scsi_print_inquiry() can print them.
 721          *
 722          * If, at some point in the future, more inquiry data is needed for
 723          * some reason, this code should use a procedure similar to the
 724          * probe code.  i.e., issue a short inquiry, and determine from
 725          * the additional length passed back from the device how much
 726          * inquiry data the device supports.  Once the amount the device
 727          * supports is determined, issue an inquiry for that amount and no

4290          * This is a gross hack.  There really aren't many other good
4291          * options (excuse the pun) for parsing options in a situation like
4292          * this.  getopt is kinda braindead, so you end up having to run
4293          * through the options twice, and give each invocation of getopt
4294          * the option string for the other invocation.
4295          *
4296          * You would think that you could just have two groups of options.
4297          * The first group would get parsed by the first invocation of
4298          * getopt, and the second group would get parsed by the second
4299          * invocation of getopt.  It doesn't quite work out that way.  When
4300          * the first invocation of getopt finishes, it leaves optind pointing
4301          * to the argument _after_ the first argument in the second group.
4302          * So when the second invocation of getopt comes around, it doesn't
4303          * recognize the first argument it gets and then bails out.
4304          *
4305          * A nice alternative would be to have a flag for getopt that says
4306          * "just keep parsing arguments even when you encounter an unknown
4307          * argument", but there isn't one.  So there's no real clean way to
4308          * easily parse two sets of arguments without having one invocation
4309          * of getopt know about the other.
4310          *
4311          * Without this hack, the first invocation of getopt would work as
4312          * long as the generic arguments are first, but the second invocation
4313          * (in the subfunction) would fail in one of two ways.  In the case
4314          * where you don't set optreset, it would fail because optind may be
4315          * pointing to the argument after the one it should be pointing at.
4316          * In the case where you do set optreset, and reset optind, it would
4317          * fail because getopt would run into the first set of options, which
4318          * it doesn't understand.
4319          *
4320          * All of this would "sort of" work if you could somehow figure out
4321          * whether optind had been incremented one option too far.  The
4322          * mechanics of that, however, are more daunting than just giving
4323          * both invocations all of the expect options for either invocation.
4324          *
4325          * Needless to say, I wouldn't mind if someone invented a better
4326          * (non-GPL!) command line parsing interface than getopt.  I
4327          * wouldn't mind if someone added more knobs to getopt to make it
4328          * work better.  Who knows, I may talk myself into doing it someday,
4329          * if the standards weenies let me.  As it is, it just leads to
