Nitin,

I think  the "Desired Data Tranfer Length" field of R2T PDU  should be
equal to
the DataPDULength
value that the initiator has sent to the target during text parameter
negotiation. Since the DataPDULength
can be different in the two directions, the initiator sends this value to
the
target as DataPDULength=<value>.
So the initiator only  sends/receives a PDU having length less than or
equal
to  the negotiated DataPDULength
(non-zero).

Any comments are welcome..
