The description is misleading, it applies only to one vxlan lwt use case (openvswitch). For other use cases, the patch has no effect. I found the current handling of route lookup results irritating, too. The reason I did not change this while doing vxlan cleanup some time ago was that I assumed we should not increase dev stats from vxlan_fill_metadata_dst. Isn't that so? Jiri
