About F-bit in ISCSI Scsi command PDU

["Prashanth.C.A. Shetty" <prashanth_ca@yahoo.com>]

Hello All,
    As per the draft definition of F-bit explained in
the iSCSI SCSI command PDU section..."F-bit should be
set to 1 when no unsolicited data follow the command
PDU".
    My interpretation of the above statement is:
    F-bit in the command PDU is to be set to 1 by the
initiator only if solicited data needs to be sent to
the Target and should be zero for Unsolicited data
transfer.
    My question:
    If I need to send only immediate
data:..[dataxferlen <=
MaxRecvPduLen,InitalR2t=True,ImmediateData=True]....What
should be the F-bit set to????.
    Should it be set to ZERO[because IMMEDIATE DATA
ONLY[InitialR2t=True,ImmediateData=True] falls as one
of unsolicited data transfer type] or should it be set
to ONE[because no unsolicited data follows the command
PDU]????
   
Regards,
Prashanth
