The Parameter Pointer field MUST be set to zero to
indicate that the Drive always transfers all supported
parameter codes for each page.
This field specifies the maximum number of bytes that
the Initiator has allocated for returned LOG SENSE data.
An Allocation Length of zero indicates that no LOG SENSE
data is sent. The Drive terminates the DATA IN phase
when Allocation Length bytes have been transferred or
when all available LOG SENSE data have been transferred,
whichever is less.

If Log Sense is issued with a Page Code = 3Eh, the Drive will return
all Log Pages in ascending order by Page Code.
