openvswitch-source - 3.1.0-2+deb12u1 main

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.
