With ML2 plugin and l2-pop mechanism driver, it's possible to locally answer to the ARP request of the VM and avoid ARP broadcasting emulation on overlay which is costly. When this functionality is enabled, the OVS flows logic evolves to [1]. This functionality was introduce in 2.1 OVS branch [2]. A README is added to describe l2-pop mechanism driver and the agents particularities.
