- ovs-vswitchd:
- The software switch now supports 255 OpenFlow tables, instead
of just one. By default, only table 0 is consulted, but the

tables. Tables 128 and above are reserved for use by the
switch itself; please use only tables 0 through 127.

+ - Flow setups are now processed in a round-robin manner across ports
+ to prevent any single client from monopolizing the CPU and conducting
+ a denial of service attack.
+ - Added support for native VLAN tagging. A new "vlan_mode"
+ parameter can be set for "port". Possible values: "access",
+ "trunk", "native-tagged" and "native-untagged".
