Comment 44 for bug 1732067

@Peter, I have confirmed it doesn't work for the case firewall_driver=iptables_hybrid. I also find it can't learn local MAC after applied this fix patch. In addition, I also find iperf3 pps test with 16 bytes UDP packet has noticeable packet loss rate.

My issue is this fix patch is just a workaround or a real fix? What issue makes br-int not to be able to learn MAC addresses? Why can we not fix this MAC learning issue? We find if one subnet isn't added into a router, MAC learning is ok, but once it is added a router, br-int won't learn VMs' MACs in other compute nodes, I think it is an ovs openflow pipeline design defect, why can't we fix this design defect and make sure br-int can learn MACs as expected.
