I see that information from 00-335r1 has been added in 00-378r0 (SPI-4
rev1 proposal). Why did changing the words in para. 2 of section
"before receiving another SPI L_Q information unit"
"before receiving another SPI information unit"
get dropped in 00-335r1? It was present in 00-335r0.
The reason u need this change is this: with the current wordings, it
ONLY talks about "before RECEIVING another SPI L_Q" and only covers
command transfers because that is the ONLY time the targer RECEIVES SPI
L_Q IUs! What is the target supposed to do if it detects an iuCRC error
in a data packet that it receives during a SCSI write? In this case,
the TARGET is SENDING SPI L_Q IUs to the initiator NOT RECEIVING it!
Also information in 10.8.3.3.3 and 10.8.3.3.4 do not address error
handling for data stream IUs. I can see that information in g) under
section 12.2 (ATN condition), para 2 in 10.8.3.3.3 and para 10 in 14.3.4
(where it mentions what to do when offset if greater than the SPI data
stream IU size) in 00-378r0 are in conflict for error handling during

~ A proposed revision 1 of SPI-4 has been posted on the t10 web site but
~ don't look for it in the drafts section. It is document number
~ titled 'Proposed content for SPI-4 rev 1'. This proposal is what the
~ recommends become SPI-4 rev 1 but because it contains some technical
~ content that was not accepted by the T10 committee it cannot be
~ as an official rev 1. For a list of that technical content look in the
~ revision 1 section at items p, q, and r.
