Dpif-netdev should not implement internal HW offload details. If need to "apply on all ports", it needs to be done in offload layer. However, in arch level, there is a problem with the proposed series. It will create a meter object per port, while in SW it is one object, that can be shared between multiple flows, on different ports.
