 Open vSwitch is a multilayer software switch licensed under the open
 source Apache 2 license.  Our goal is to implement a production
 quality switch platform that supports standard management interfaces
-(e.g. NetFlow, RSPAN, ERSPAN, IOS-like CLI), and opens the forwarding
-functions to programmatic extension and control.
