/* The IP64 special ports module allows specific ports on the IP64
   translator to be mapped to specific address in the IPv6
   network. The module provides three function prototypes that must be
   implemented by the user.

   The IP64 special ports module must be enabled by

#define IP64_SPECIAL_PORTS_CONF_ENABLE 1

   Otherwise, the functions are replaced by empty default definitions
   in the ip64-special-ports.c module.

   Port numbers are always in network byte order. */
