Public bug reported:
Description
===========
We started to experience instance build failures relating to port
binding failure on our 2024.1 system (with VF-LAG), relating to
```
Refusing to bind due to unsupported vnic_type: direct with no switchdev
capability bind_port
```
and this information was missing from nova's pci_devices table:

Nova should be correctly assigning VF capabilities following this patch:
https://review.opendev.org/c/openstack/nova/+/884439, and in our case the DB

Steps to Reproduce
==================
* create an instance with VF-LAG SRIOV 'direct' NIC
* restart nova-compute on that hypervisor
* delete instance
and then the VF in the pci_devices table is left with incomplete
capabilities
Expected Result
===============
The VF entry in pci_devices should contain the full set of capabilities
DB output
=========
This is the expected content of the DB before attach, during, and after

Title:
nova-compute restart stripping VF capabilites on VF unbind
Status in OpenStack Compute (nova):
New
Bug description:
Description
===========
We started to experience instance build failures relating to port
binding failure on our 2024.1 system (with VF-LAG), relating to
```
Refusing to bind due to unsupported vnic_type: direct with no switchdev
capability bind_port
```
and this information was missing from nova's pci_devices table:
```

```
Nova should be correctly assigning VF capabilities following this patch:
https://review.opendev.org/c/openstack/nova/+/884439, and in our case the DB
entry for a VF should like like:
```

Steps to Reproduce
==================
* create an instance with VF-LAG SRIOV 'direct' NIC
* restart nova-compute on that hypervisor
* delete instance
and then the VF in the pci_devices table is left with incomplete
capabilities
Expected Result
===============
The VF entry in pci_devices should contain the full set of capabilities
DB output
=========
This is the expected content of the DB before attach, during, and after
```
