commit cef3b5ef2cc1fe983578e4966208cf95fdea5880 Author: Alexey Stupnikov <[email protected]> Date: Thu May 25 21:23:32 2023 +0200 Translate VF network capabilities to port binding Libvirt's node device driver accumulates and reports information about host devices. Network capabilities reported by node device driver for NIC contain information about HW offloads supported by this NIC. One of possible features reported by node device driver is switchdev: a NIC capability to implement VFs similar to actual HW switch ports (also referred to as SR-IOV OVS hardware offload). From Neutron perspective, vnic-type should be set to "direct" and "switchdev" capability should be added to port binding profile to enable HW offload (there are also configuration steps on compute hosts to tune NIC config). This patch was written to automatically translate "switchdev" from VF network capabilities reported by node device driver to Neutron port binding profile and allow user to skip manual step that requires admin privileges. Other capabilities are also translated: they are not used right now, but provide visibility and can be utilized later.

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.
