Hi, Kevin. If I load openvswitch and linuxbridge mechanism drivers in neutron server, and running ovs-agent in compute nodes. What does openvsitch mechanism driver do? What does linuxbridge mechanism do? I think there must have some differences between the openvswitch and the linuxbridge mechanism driver. But I can't get the exact point about the two mechanism drivers when running ovs-agent in compute nodes now.
