    tcp: Restore 6 tcps padding entries in HEAD
    
    The padding in CURRENT shall not shrink. It is
    designed that in CURRENT at always stays
    the same, and then when a new stable is branched, it
    inherits 6 pointer placeholders that can be used
    withing this stable/X lifetime to extend the structure.
