IPStack - Routing improvement

- When creating an boot config, routes are set up too
 > TODO: Implement a static route for each interface (as part of
   tInteface), removing the need to set a route when creating.
 > Problem, maintaining?
 > No real problem, just not have those in the main route list (if
   you want an interface route to be more important than another,
   just set it manually)
