[RFE] OVN support for vnic type virtio-forwarder

[Yifan Li]

Problem Description

The current neutron OVN plugin does not supports vnic type virtio-forwarder,
which is supported by Nova.

Reference:
https://specs.openstack.org/openstack/nova-specs/specs/pike/implemented/netronome-smartnic-enablement.html

Proposed Change

Implement the functionality of supporting vnic type virtio-forwarder in neutron
OVN mech driver. The neutron will generate a detailed vif and send it to nova
when a virtio-forwarder vnic is requested.

The existing vnic types support in OVN plugin will not be impacted. Other network
plugins also will not be impacted.

Seems like a valid RFE.

Yifan - will you be able to attend a Neutron Drivers meeting to discuss this?

[Yifan Li (skingfd)]

Hi Haley:

Of course, I am able to attend it. The next Neutron Drivers meeting is at
14:00 UTC 9/9, right?

Best wishes,

Hi Haley,

I'm sorry but it is the first time I take apart into the opendev
community meeting. So I want to make sure that it is a text meeting on OFTC
Web IRC rather than voice based meeting, right?

Best wishes,

Hi, yes, the meeting is at 14:00 UTC 9/9 on OFTC IRC, not a video meeting.

Fix proposed to branch: master
Review: https://review.opendev.org/c/openstack/neutron/+/856441

[Yifan Li (skingfd)]

Hi all, I have already prepared an implementation, and I have submitted the code https://review.opendev.org/c/openstack/neutron/+/856441

[Lajos Katona (lajos-katona)]

We discussed this RFE and agreed that this is really good idea, see the meeting logs:
https://meetings.opendev.org/meetings/neutron_drivers/2022/neutron_drivers.2022-09-09-14.00.log.html#l-13

Just a note that we are over Zed Feature Freeze, this patch can't be merged in Zed cycle, only for 2023.1 / Antelope

    [OVN] Adding support for VNIC type virtio-forwarder.

    The virtio-forwarder related code has already been written in other
    neutron components except OVN. Added logic solving virtio-forwarder
    in OVN plugin.Add unit tests of virtio-forwarder VNIC type. Test
    cases include test_create_port_with_vnic_virtio_forwarder,
    test_bind_virtio_forwarder_port_geneve,
    test_bind_virtio_forwarder_port_vxlan.
