Hi,
If no configure of "datapath-id" in other_config of br, then it will
choose the minimum non-local MAC address among all of the ports in bridge. The
relevant code is in the find_local_hw_addr
function（https://github.com/openvswitch/ovs/blob/master/vswitchd/bridge.c#L2322）.
In this case, If a new port with miner mac, it will change the dpid ,and
the mac of br-int. It will cause frequently reset with SDN controller by
ofproto_set_datapath_id function.
Is this reasonable？
Thanks,
Yun
