Currently, __ip_route_add() mistakenly always sets VRF table to RT_TABLE_MAIN - this seems to have sneaked in during unsigned-md5 tests debugging. That also explains, why ip_route_add_vrf() ignored EEXIST, returned by fib6. Yet, keep EEXIST ignoring in bench-lookups selftests as it's expected that those selftests may add the same (duplicate) routes.
