 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

3609          * options (excuse the pun) for parsing options in a situation like
3610          * this.  getopt is kinda braindead, so you end up having to run
3611          * through the options twice, and give each invocation of getopt
3612          * the option string for the other invocation.
3613          *
3614          * You would think that you could just have two groups of options.
3615          * The first group would get parsed by the first invocation of
3616          * getopt, and the second group would get parsed by the second
3617          * invocation of getopt.  It doesn't quite work out that way.  When
3618          * the first invocation of getopt finishes, it leaves optind pointing
3619          * to the argument _after_ the first argument in the second group.
3620          * So when the second invocation of getopt comes around, it doesn't
3621          * recognize the first argument it gets and then bails out.
3622          *
3623          * A nice alternative would be to have a flag for getopt that says
3624          * "just keep parsing arguments even when you encounter an unknown
3625          * argument", but there isn't one.  So there's no real clean way to
3626          * easily parse two sets of arguments without having one invocation
3627          * of getopt know about the other.
3628          *
3629          * Without this hack, the first invocation of getopt would work as
3630          * long as the generic arguments are first, but the second invocation
3631          * (in the subfunction) would fail in one of two ways.  In the case
3632          * where you don't set optreset, it would fail because optind may be
3633          * pointing to the argument after the one it should be pointing at.
3634          * In the case where you do set optreset, and reset optind, it would
3635          * fail because getopt would run into the first set of options, which
3636          * it doesn't understand.
3637          *
3638          * All of this would "sort of" work if you could somehow figure out
3639          * whether optind had been incremented one option too far.  The
3640          * mechanics of that, however, are more daunting than just giving
3641          * both invocations all of the expect options for either invocation.
3642          *
3643          * Needless to say, I wouldn't mind if someone invented a better
3644          * (non-GPL!) command line parsing interface than getopt.  I
