### Contribution description
If the fib contains a route to a subnet via another host, it can not be on-link.
Consider fib entries when deciding whether an address is on-link.
If a route via another host is a stronger match than an on-link prefix, the address must be off-link.

- which test/example to compile for which board and is there a 'test' command
- how to know that it was not working/available in master
- the expected success test output
