Description of problem:

A non br-ex LACP bond with VLAN has no IP addresses after ovs-configuration service start from last reboot when using NMstate configuration at day1.

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

Any 4.14 nightly version after 4.14.0-rc.6

How reproducible:

Always

Steps to Reproduce:

1. Prepare NMstate settings to add in the install-config.yaml using dual-stack through DHCP for LACP bond0 (br-ex), bond0.vlanX (storage), bond1.vlanY (secondary bridge br-ex1)
2. Deploy OCP 4.14 with latest nightly on a baremetal cluster with IPI and OVN-K
3. After deployment confirm all the interfaces have dualstack (br-ex, bond0.vlanX, br-ex1)
4. Reboot a node, after ovs-configuration service finishes, the br-ex and br-ex1 have dualstack addresses, except bond0.vlanX, which has nothing.

Actual results:

Any bond.vlanX (non br-ex or br-ex1) connection is not active

Expected results:

Any bond.vlanX (non br-ex or br-ex1) connection starts correctly after a reboot

Additional info:

- This works fine using 4.14.0-rc.6 and previous releases
- This also works fine when setting up network with MachineConfigs manifest at day1

More details:

We have observed that the bond0.vlanX (which is for our storage network) does not get any IP address after a reboot from applying a PAO profile, but again only with releases after OCP 4.14.0-rc.6

This is a working cluster using 4.14.0-rc.6

This is a cluster with the failure, using latest nightly available 4.14.0-0.nightly-2023-10-25-223202

Also the interesting part is that there are other connections, bond0 for br-ex, and bond0.vlanY for br-ex1 and they work fine, they have the same configuration as bond0.vlanX and bond0.vlanX is not active

For example, this is from the cluster with the failure, and bond0.360

[core@worker-0 ~]$ sudo diff /etc/NetworkManager/system-connections/bond0.360.nmconnection /etc/NetworkManager/system-connections/bond0.662.nmconnection 
4,5c4,5
< id=bond0.360
< interface-name=bond0.360
---
> id=bond0.662
> interface-name=bond0.662
7c7
< uuid=67bd5745-a6c1-5c61-b27c-2a6958b3a777
---

36c36
< id=360
---
> id=662

[core@worker-0 ~]$ nmcli con show --active | grep bond0.360
[core@worker-0 ~]$

Finally, in the ovs-configuration service from the last reboot, we can see that when the service start it shows the bond0.360 has both IPv4 and IPV6, but when it finishes it shows no IP addresses at all.
