    Localize protocol attributes into a LinkProtocol class
    
    Several constants vary depending on our link protocol version. Rather than
    encoding a bunch of 'x if link_protocol > y else z' conditionals centralizing
    this in a LinkProtocol class.
    
    LinkPrococol.for_version() normalizes an integer *or* LinkProtocol into a
    LinkProtocol.
    
    Pattern we should follow is:
    
      * Public methods should always accept an integer.
    
      * Any time we use or store a link protocol version it's normalized to a
        LinkPrococol class.
