iSCSI: Login stage transition; T bit

[Luben Tuikov <luben@splentec.com>]

Hello there,

Q1. It appears to be the case that 
   o  CSG =/= NSG iff T=1, and 
   o  CSG < NSG, from the table on pg. 64, v11.

Thus, T=1 iff CSG < NSG, so the T bit can be retired,
by imposing that there be no garbage in NSG (that is
NSG >= CSG for all login PDU's).

Q2. After a request/response with T=1 and NSG > CSG
(appropriately), what is the RFC verb for
the initiator. That is, MUST the initiator switch
to the next stage, or SHOULD or MAY?

Q3. Same as Q2 but NSG=3?

Thanks,
