/* INQUIRY notes:
* It is recommended that the initial allocation length given to a
* standard INQUIRY is 36 (bytes), especially if this is the first
* SCSI command sent to a logical unit. This is compliant with SCSI-2
* and another major operating system. There are devices out there
* that use one of the SCSI commands sets and lock up if they receive
* an allocation length other than 36. This technique is sometimes
* referred to as a "36 byte INQUIRY".
*
* A "standard" INQUIRY is one that has the EVPD and the CmdDt bits
* clear.
*
* When doing device discovery on a SCSI transport (e.g. bus scanning)
* the first SCSI command sent to a device should be a standard (36
* byte) INQUIRY.
*
* The allocation length field in the INQUIRY command was changed
* from 1 to 2 bytes in SPC-3, revision 9, 17 September 2002.
* Be careful using allocation lengths greater than 252 bytes, especially
* if the lower byte is 0x0 (e.g. a 512 byte allocation length may
* not be a good arbitrary choice (as 512 == 0x200) ).
*
* From SPC-3 revision 16 the CmdDt bit in an INQUIRY is obsolete. There
* is now a REPORT SUPPORTED OPERATION CODES command that yields similar
* information [MAINTENANCE IN, service action = 0xc]; see sg_opcodes.
