If we delay route-to/dup-to/reply-to through dummynet we are eventually returned to pf_test(). At that point we no longer have the context for the route-to destination. We'd just skip the pf_test() and continue processing. This means that route-to did not work as expected. Extend pf_mtag to carry the route-to destination so we can apply it when we re-enter pf_test().
