I'm reopening this because I believe the fix committed fixes only part of the problem. With firewall_driver=noop the unnecessary ingress flooding on br-int is gone. However we still have the same unnecessary flooding with firewall_driver=openvswitch. For details and a full reproduction please comments to bug #2048785:
