It's not used for anything, and not useful for anything. It is mostly historical. A Linux kernel Open vSwitch datapath needs to have a port named the same as the datapath. Open vSwitch needs one datapath, and it names it ovs-system, so there's a port with the same name, even though it doesn't get used for anything. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
