DTYPE_FLOPPY in the default disklabel.

which were setting xs->resid.

member of 'struct scsi_xfer' has always been pointed at the 'struct scsi_generic
cmdstore' member of the same instance. So nuke 'cmdstore' and remove the '*'
from cmd. Take the address of cmd as required by the various casts.

favour of simply using the device's claimed SCSI level of support. Except of
course for ATAPI/USB devices which often don't claim anything. Keep assuming
they are at least SCSI-2. Use consistant tests in

initialize the scsi_link's on the bus. After sucking this information
out of the "prototype" link provided by the scsibus_attach_arg, no

'adapter_target' to a value greater than or equal to

Add SDEV_NO_ADAPTER_TARGET (0xffff), a value guaranteed to

pointers returning possible block descriptor values for block size,
block count and density. Most calls were passing "NULL, NULL, NULL"

Call scsi_parse_blkdesc() directly in those few cases where one or

scsi_all.h.
Add scsi_read_cap_10() and scsi_read_cap_16() functions to
scsi_base.c, i.e. move logic to do actual READ_CAPACITY commands out
of sd_read_cap() and sd_read_cap_16().
This will allow the READ_CAPACITY code to be reused by cd(4).
Return -1 for errors where the error code is just discarded, reducing
ENOMEM, ENXIO, EIO uses.

outside scsi_base.c.
this will allow adapters to restrict access to iopool resources
based on some state, and then kick the pending requests on the pool
when the state comes good again.
ive been avoiding this for a long time, but it is the least worst
way to deal with some uses of XS_NO_CCB.
discussion with kettenis@ helped me decide this was right.

to cd.c and call it cd_size(), like sd_size() lives in sd.c.
