iscsi Rev 7.93 : text cmd & bookmarks.

[Santosh Rao <santoshr@cup.hp.com>]

Hi Julian,

Thanks for adding the target transfer tag field to the text command
& text response. This allows for simpler indexing for targets without
having to special case the text message lookups.

Also, as you've observed and incorporated, the target transfer tag field
itself serves as a bookmark and so, the bookmark field has been removed.

One question remains however. Since the target transfer tag field serves
as a bookmark and a TTT of 0xFFFFFFFF serves as an indication that this
is a new text command (i.e. no bookmark present), of what value add is
the bookmark bit ? Why not remove the bookmark bit itself and only use
the TTT ?

Keeping both the bookmark bit and the TTT is providing 2 ways of
indicating a new text cmd. I would be in favor of removal of the
bookmark bit.

Regards,
Santosh
