SRIOV Overlay Networks:
Required features in SRIOV Overlay networking:
- Currently, OVN4NFV by default create the Veth pair interfaces for all interfaces.
- SRIOV Overlay networks introduce a feature to include the interfaceType in the OVN networking and provide the deviceplugin sock name and targets on the devices only having SRIOV hardware-enabled labels
