Public bug reported:

OVS hardware offload was originally intended to be a feature used by
normal users. But bugfix
https://review.opendev.org/c/openstack/neutron/+/499203 for bug #1713590
removed the ability for non-admins to use OVS hardware offload without
changing neutron default policy in a non-secure manner: "switchdev"
capability must be added to port binding profile after port is created.

At the same time, libvirt node device driver reports "switchdev"
capability and we can translate it from NIC PCI device object to port
binding profile when port is attached.
