Given a system administrator needs to configure network interfaces consistently across systems where NIC names may change and uses Nmstate to manage the network state, When they define an interface in the desired state YAML by setting the identifier field to pci-address and providing a valid pci-address value, Then Nmstate must correctly match the interface associated with the provided PCI address at runtime and apply the declared configuration or fail gracefully with a clear error message if no matching PCI device is found. Integration test case is available upstream Code is reviewed and merged upstream Preliminary Testing is done Upstream documentation is written in the upstream MR if needed Release Notes text is written in the RHEL issue if needed A demo is recorded

.Nmstate can assign settings to network interfaces based on PCI addresses With this enhancement, you can use Nmstate to set up network interfaces based on their PCI address instead of a device name. Use this feature to ensure consistent configuration across nodes in a cluster.
