    FCencap: List ALL SOF/EOF codes



    Upon further reflection, I think the right thing to do
    is to list all the SOF/EOF codes defined in FC-BB in
    the FC Encapsulation draft.
    
    FIRST
    
    There is nothing in the FC Encapsulation draft other
    than to omission of Class 1 SOF/EOF codes that prevents
    encapsulating FC Class 1 frames for TCP transport.
    Sure, a TCP ULP that is smarter than anything anybody
    has thought about will be required to do it.  BUT
    there is (or should be) nothing the the FC Encapsulation
    draft that prevents such a protocol from being invented.
    AND the FC Encapsulation draft specifically says that
    you need the wisdom of some other protocol document in
    order to get any use out of the FC Encapsulation draft.
    Why force the mad man that devises a way to transport
    Class 1 over TCP/IP to revise the FC Encapsulation
    SOF/EOF tables?
    
    SECOND
    
    It is conceivable that a future version of iFCP
    (or maybe even FCIP) might want to support Class 4.
    Again, there is nothing in the FC Encapsulation
    draft that prevents this, except the omission
    of the SOF/EOF codes.
    
    FINALLY
    
    I believe that the elimination of all SOF/EOF
    codes other than Class 2, Class 3, AND CLASS F
    is a hold over from the early FCIP work, before
    the FC Encapsulation was split into a separate
    draft. I believe that decision was right for
    FCIP but wrong for an FC Encapsulation intended
    to be used by ALL FC protocols running over
    TCP/IP.
    
    Thanks for your consideration.
    
    Ralph...
