<Draft co-author hat on>

I wanted to extract this change from Mallikarjun's long list of normative changes to call it out for attention.

The important question is: Is "6" the right number of exchanges that SHOULD be allowed?
There's nothing special about that number ... it "seemed like a good idea at the time".

Alternate suggestions are welcome, especially if this change could cause any problems for current implementations.

Section 6.2
[from]
An iSCSI initiator or target MAY terminate a negotiation that does not end within a reasonable time or number of exchanges.

[to]
An iSCSI initiator or target MAY terminate a negotiation that does not terminate within an implementation-specific reasonable time or number of exchanges, but SHOULD allow at least 6 exchanges.

Thanks,
