iscsi: Data PDU in two Sequence multiplexing issue

[Sanjay Goyal <sanjayg@ivivity.com>]

Hi,
Can somebody please comment,
 
This is what I am not very clear about, from the specification.
-----------------
10.8 says: Within a connection, outstanding R2Ts MUST be
fulfilled by the initiator in the order in which they were received.

3.2.4.1 says: When unsolicited data is used, the order of the unsolicited
data on each connection MUST match the order in which the commands
on that connection are sent. Command and unsolicited data PDUs may
be interleaved on a single connection as long as the ordering
requirements of each are maintained (e.g., command N+1 MAY be sent
before the unsolicited Data-Out PDUs for command N, but the
unsolicited Data-Out PDUs for command N MUST precede the unsolicited
Data-Out PDUs of command N+1).
------------------


if we have two Data-out sequences A and B of 2 pdus each, to be sent on the
same connection.
this is how I think they will be sent
PDU 1 of A -> PDU2 of A  -> PDU1 of B -> PDU2 of B
  What I am trying to verify is that the below sequence is valid or not. 
PDU 1 of A  -> PDU 1 of B -> PDU2 of A -> PDU2 of B
