define Package/openvswitch/Default/description
  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, 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.
