[RFE] add new extension "device-profile" for port

[Xinran WANG]

A device_profile is a notion of Cyborg project, please refer to https://docs.openstack.org/api-ref/accelerator/v2/index.html#device-profiles

It is a named set of user requirements for one or more accelerators. It can be viewed as a flavor for devices. Broadly it includes two things: the desired amounts of specific resource classes and the requirements that the resource provider(s) must satisfy.

Neutron needs to add a new extension "device_profile" which filled by the name of a device profile indicating an accelerator that can be associated with a neutron port, in order to offload some networking workload on the smartnic.

Please refer to nova spec for the details:

Related spec is https://review.opendev.org/c/openstack/nova-specs/+/742785/14/specs/wallaby/approved/support-sriov-smartnic.rst right?

Yes, thanks for providing the link. Please see the latest patchset https://review.opendev.org/c/openstack/nova-specs/+/742785/15

We discussed that RFE on today's drivers meeting and we decided to approve it. As it is pretty simply change, I don't think we will need separate spec for that. Lets cover that in that nova's spec only.

This implementation could achieve by changing the POC code to meet the Spec requirements.

Per spec: https://review.opendev.org/c/openstack/nova-specs/+/742785/14/specs/wallaby/approved/support-sriov-smartnic.rst#191

In the neutron part, we need a new vnic_type: cyborg

"vnic_type":"cyborg".
