information in the TOC. The partition info is just overwritten or
rendered incomplete by readdisklabel().
Just examine the TOC to determine if the cd is audio only, i.e. it has
a valid TOC but no data tracks. In this case don't call
readdisklabel(). Much simpler code. No functional change for single
data track CD's like the install media.

1) Using cd_load_toc() instead of replicating code.
2) Using struct cd_toc and betoh32() like other parts of cd.c.
3) Restoring pre-Sept. 26 behaviour of trying to read usable disklabel
info if there is no TOC. i.e. avoid readdisklabel() only when it is an
audio-only CD. Stop abusing spoofonly.

Add a check for ending_track < starting_track before calculating size
of TOC to read.

bzero() all malloc'ed cd_toc structs because cd_read_toc() will only
zero as much as it is trying to read.

sd does. Prevents spurious label information from being seen on
devices that return NOT READY/UNABLE TO RECOVER TABLE-OF-CONTENTS

works.

ILLEGAL REQUEST is correctly reported for blank media, as an
informative FreeBSD comment pointed out. Ensure the returned table of
contents is always initialized to zero. Call readdisklabel with
spoofonly = 1 when no data tracks are found.
Don't try to read the DOS label from the device if spoofonly is 1.
Only done for amd64 here. More archs to follow.
Eliminates scsi error messages when attempting to open a cd containing
blank media, as pointed out by Michael Coulter.

required number of bytes, rather than a full scsi_mode_sense_buf. Some
devices (e.g. my HP SureStore DAT/24) decline to accept such oversized
transfers. Instead, force callers to fill in the data_length field in
the header and use that information to set the size of the transfer.

Add 'big' parameter to report which mode sense header type is being
returned. Eliminate icky pointer arithmetic, since it won't work if
only block descriptors are returned by the device.

is trying to bring in.
1) Change name of SDEV_NOCDB6 to SDEV_ONLYBIG to align it with the
same quirk in NetBSD, and make it more clear what it is trying to do.
i.e. force the use of READ_BIG/WRITE_BIG commands, not suppress all
use of 6 byte CDB's.
2) Check SDEV_ONLYBIG in cd.c as well as sd.c. i.e. both places where
a choice is made to use the 6 or 10 byte versions of READ/WRITE.
3) Actually make use of the ADEV_NOTUR (No TEST UNIT READY) quirk to
suppress the emission of TEST UNIT READY commands.
4) Add some explanatory comments from NetBSD to scsiconf.h so that the
use of the quirks is made clear.

This fixes some instances of both behaviours, and sets the stage for some

Use increased retries number and don't ignore SCSI_IGNORE_NOT_READY
when call scsi_test_unit_ready() for cd-rom, this makes system wait
if drive is loading media.
