Byte 04 - Allocation Length

The Allocation Length specifies the number of bytes that the initiator

has allocated for the return of inquiry data. A value of 0 indicates that

no inquiry data is to be transferred and is not an error.

The CTS terminates the Data In phase when the number of bytes

specified in the Allocation Length field has been transferred or when

all available inquiry data has been transferred, whichever is less.

The amount of inquiry data returned by the CTS depends on the type

of data being returned, as follows:

Up to 6Ah (106) bytes for the Standard Inquiry Data Table

06h (6) bytes for the Supported Vital Product Data Page

0Eh (14) bytes for the Unit Serial Number Page

Byte 05 - Bits 7 and 6 - Vendor Unique

There are no vendor unique definitions for this command.
