Re: iSCSI: draft 7: Final bit in Data PDUs

Elliot,

I have no clue how those commands are going to work.
Can you help?
I assume that the F bit will have to be there at both ends?

Subject:  iSCSI: draft 7: Final bit in Data PDUs



iSCSI draft 7 section 2.7.1 describes when the (F) Final bit is
set in the Data-out and Data-in PDUs:

  For outgoing data, this bit is 1 for the last PDU of unsolicited
  data  or the last PDU of a sequence answering a R2T.

  For incoming data, this bit is 1 for the last input (read) data
  PDU of a sequence.

It needs to define how this works for bidirectional commands.
Is the F bit set to one on both the last Data-out PDU and the last
Data-in PDU?  Or is it set to one only on the last Data PDU,
whatever direction it may be?
