iSCSI: draft 7: remove S bit and Status field from the Data-in PDU?

["Elliott, Robert" <Robert.Elliott@compaq.com>]

At the IETF IPS WG meeting, removing the immediate data from the
Command PDU was discussed as a possible simplification.

A similar simplification would be to remove the S bit and Status
field from the Data-in PDU.  These let Status be returned in the
Data-in PDU rather than in a separate Response PDU.  The target
can send the last Data-in PDU and the Response PDU back-to-back; 
there's not much wire overhead sending 48 more bytes.  The 
initiator always has to handle separate Response PDUs, so this 
eliminates a special case and collects all status and residual 
handling in one place.
