Editorial comments - Digest

["Amir Shalit" <amir@astutenetworks.com>]

Based on the PDU Template, the iSCSI PDUs consists of:

BHS
AHS's (optional)
Header Digest (optional)
Data Segment (optional)
Data Digest (optional)

Some of the individual command formats do not follow the PDU Template, or
imply that -both- the Header and Data Digests (if any) precede the Data
Segment:

SCSI Response:
BHS
Digests if any...
Data Segment (optional)

SCSI Response should be (similar to SCSI Command format and others):
BHS
Header Digest (if any, or optional)
Data Segment (if any, or optional)
Data Digest (if any, or optional)

Some other examples are:
SCSI Data-out PDU for WRITE operations (READ operation PDU format is ok).
Asyncronous Message
Text Request
Text Response
NOP-Out
NOP-In

Also for Header only iSCSI PDUs "Digests (if any)" should be changed to
"Digest (if any)" or "Header Digest (if any)":
Task Management Function Request
