But it is only a problem for devices that require us to set values in
cdb[1] that conflict with the scsi spec, not for all devices that have
vendor specific commands.
Do the devices in question that don't want the LUN in cdb[1] report as
scsi-3 or later? If so we can still pass through the scsi level and it
would work fine. Yeh, if we later hit scsi-2 devices that want it we
have a problem.
