Re: iSER use of ITT in Data_Completion_Notify

I don't know what you mean by "the target does not need to catalog the
ITT".  Both the R2T and the SCSI Data-in PDU generated by the iSCSI layer
contained the ITT.

That is true but it would be better if the TTT were supplied for the target

to identify the structure used for the data. That way the target does not
need to catalog the ITT. The TTT could just be an index or a pointer that
can be resolved quite easily.
