Current packet processing openvswitch-agent in br-tun is based on tun-id, as a consequence, two networks using different tunnel types but sharing the same tun-id would not be properly isolated.
To ensure proper isolation within a single bridge, NORMAL action can't be used any more as it floods unknown unicasts on all bridges ports. It is replaced by a learn action that dynamically sets-up flows when packets are recieved from tunnel ports. As mac address are learnt in explicit flows (in table 20), we can use a default action in that table to flood unknown unicasts to the right set of ports, like broadcasts and multicasts packets.
