      User story:

      As a network administrator, I want NetworkManager to recognize and match 802-3-ethernet.mac-address for system interfaces in an OVS bridge configuration, so that I can manage OVS bridge connections more effectively and ensure consistent network behavior across different interface configurations.

      Acceptance criteria:

      Given a system adminstrator configuring a system with NetworkManager, OVS installed, and a virtual Ethernet device eth1, 

      When they configure eth1 within an OVS bridge br0 using NetworkManager commands to utilize the MAC address for matching rather than the interface name,

      Then, eth1 should be successfully added to br0 and operate correctly.

      Definition of Done:

      • The implementation meets the acceptance criteria
      • Integration tests are written and pass 
      • The code is part of a downstream build attached to an errata
      • The changes are documented

      What were you trying to do that didn't work?

       

      NetworkManager allows `802-3-ethernet.mac-address` to match a interface instead of `connection.interface-name`. If works well for bond and linux bridge port, but not works for OVS bridge system interface.

      Please provide the package NVR for which bug is seen:

      Expected results

       
      eth1 been assigned to OVS bridge br0 as system interface
