It's good. If get_port_by_name in dpif-netdev use string hash replace of HMAP_FOR_EACH the performance would better.

I think that it's the dpif itself that should really be doing the check (the kernel datapath especially needs to do this for itself), so I sent an alternative patch that works that way: https://patchwork.ozlabs.org/patch/932991/ Will you test it?
