iSCSI: SNACK R2T/Data

[Michael Schoberg <michael_schoberg@cnt.com>]

Old subject, but I couldn't find any discussion on this:

When does the target know it no longer needs to hold R2T & Data PDUs?
StatSN responses are acknowledged through the ExpStatSN field received in
future I->T requests.  What's the acknowledgement method for R2T & Data
PDUs?  Is it tied to the original request and acknowledged through the
ExpStatSN acknowledgment of the request's response?

Thanks.
