Ido Schimmel 707c1f866c selftests: fib_tests: Add test cases for route lookup with oif
Test that both address families respect the oif parameter when a
matching multipath route is found, regardless of the presence of a
source address.

Output without "ipv6: Select best matching nexthop object in
fib6_table_lookup()" and "ipv6: Honor oif when choosing nexthop for
locally generated traffic":
