openvswitch-controller 2.0.1+git20140120-0ubuntu2 (ppc64el binary) in ubuntu trusty

 Open vSwitch is a production quality, multilayer, software-based,
 Ethernet virtual switch. It is designed to enable massive network
 automation through programmatic extension, while still supporting
 standard management interfaces and protocols (e.g. NetFlow, IPFIX,
 sFlow, SPAN, RSPAN, CLI, LACP, 802.1ag). In addition, it is designed
 to support distribution across multiple physical servers similar to
 VMware's vNetwork distributed vswitch or Cisco's Nexus 1000V.
 .
 The Open vSwitch controller enables OpenFlow switches that connect to it
 to act as MAC-learning Ethernet switches.
