[5] The Allocation Length specifies the number of bytes that the initiator has allocated for returned Mode
Sense data. An Allocation Length of zero indicates that no Mode Sense data shall be transferred. This
condition shall not be considered as an error. Any other value indicates the maximum number of bytes
that shall be transferred. The drive shall terminate the Data In phase when allocation length bytes have
been transferred or when all available Mode Sense data has been transferred to the initiator, whichever is
less.
