does not apply to information contained in other

* - https://datatracker.ietf.org/doc/html/rfc4861#section-4.2
* So (after default router list was tested),
* send a RA with Router Lifetime value of zero.
* to test that _handle_rtr_timeout follows this behavior.
* If it doesn't, the following tests for RA options will fail.
