    IPV6 - Attempt to fix tcp46 compatibility listen sockets
    
    * When creating the accepted socket via the syncache, if the
      listen socket is INET6 but allows compatibility connections
      the inp created via sonewconn() will probably set IN6P_IPV6_V6ONLY.
    
      This flag must be cleared if the incoming connection is
      actually IPV4, otherwise tcp6_soport() will not properly
      fall through to tcp_soport().
    
    * NOTE: Even though the connection is IPV4 the socket's protocol
      is copied from the listen socket which is INET6.  This seems
      to work ok but it isn't ideal.
    
    * When connecting make sure that IPV6 connections use cpu 0 for
      now (we don't have a proper hash for IPV6 addresses yet).
