    RE: iscsi : default iscsi mode page settings.



    
    Does anyone know of where a Legacy function would exist, in the Host which
    would do anything with FirstBurstSize?  I am assuming it would have to be
    in the SCSI Device Driver, and since we have iSCSI instead, that may not be
    an issue.
    I could be wrong but I do not think that it occures in the SCSI Class
    Drivers.
    And I do not think it ocures in the File Systems, so where does this Legacy
    function we are worried about occure?
    If it is in the SCSI Device Driver it is NOT an issue.

    Anything iSCSI specific should attempt to follow other iSCSI
    methods of configuration (e.g. text keys).  We should really
    be driving towards a single method of parameter negotiation
    and configuration - especially when the legacy methods
    have no clue about the new parameters and would require upgrades.
