Re: iSCSI: Login stage transition; T bit

Thanks Julian.

> +++ it must switch as the initiator is the one that requested it.

Do you think that it will be a good idea that this sentence
be included in the draft, since it makes the requrements
explicit. I.e.:

That is, if a req and resp stage transition sequence is communicated,
i.e. T=1 and NSG > CSG, then the initiator MUST switch to NSG, i.e.
the next PDU has to be an I->T PDU AND it MUST carry
a CSG = NSG(of the sequence). The target MUST close
the connection if such a PDU is not received, that is
a different PDU was received, after the stage transition sequence communication.

Comments on the above paragraph, appreciated.

Ok, no more improvement on the T bit. But as a side note:

> +++ yes it is redundant but intentionally so NSG hast to be 0 if T is not 1 +++

The text says that if T = 0 then NSG is reserved. That is it is invalid
whatever the value therein. T <==> NSG, thus the redundancy.
