Added the following under iSCSI Requirements Last Call Issues:

	The general sense of the room was that data formats and the like
ought
	not to be changed - at this point in the process, stability matters,
	and further changes of this sort need to be discussed on the list
prior
	to being made.

While I don't believe consensus was called on this, I do remember it as the
"general
sense of the room".

That topic was picked up again in the error recovery session.  In essence,
if ESP is in
use, CRC failures at the iSCSI level will essentially never happen, allowing
at least
within-session and within-connection (and presumably) within-command
recovery
to be dropped, but the HMAC in ESP is computationally expensive leading to
the
interest in a CRC shim.  I've added explanation of this to the point in the
error
recovery session where the CRC shim was discussed.
