openvswitch-source 2.12.90~git20200107.af683565b-0ubuntu1 (amd64 binary) in ubuntu focal

 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.
 .
 This package contains the full Open vSwitch source code to support
 use with the Open Virtual Network (OVN) build.
