NMState config being applied to the nodes

Description of problem: There seems to be a problem when creating an ovs-bridge with copy-mac-from and assigning its address with DHCP. After rebooting, some of my nodes are requesting an address using a different MAC from the one the bridge was supposed to copy. Others correctly use the copied MAC. In both cases the MAC was set correctly, but it appears there is a timing issue with the DHCP request where sometimes the MAC is set after the request has been sent.

I'm not sure whether this is an NMState issue or a NetworkManager one, but since I can't figure out where NMState is overriding the MAC it's difficult to provide a reproducer for NetworkManager in isolation.


Version-Release number of selected component (if applicable): 2.2.13


How reproducible: About 50% of the time in my experience.


Steps to Reproduce:
1. Apply NMState ovs-bridge config with copy-from-mac set to the underlying physical interface.
2. Reboot node

Actual results: 50% of the nodes will request a DHCP address using the wrong MAC address and get a different IP than they did when NMState initially created the bridge.


Expected results: Nodes all get the same address they had before the reboot.


Additional info: I will attach the NMState YAML and NM trace logs for both a node that did get the same address as well as one that demonstrates the problem.
