[Bug 1965660] [NEW] IPoIB interface is not coming up during boot (cloud-init/NetworkManager)

Public bug reported:

I am trying to create in OpenStack setup a Centos8-Stream VM with IPoIB interfaces.
image was created with cloud-init and dhcp-all-interfaces.
And I see that the interface is not configured automatically to be a "connected" interface by NetworkManager during boot and therefore not pulling DHCP.
Only when I run the command "mcli conn add type infiniband con-name ib0 ifname ib0" the interface becomes active and assigned with DHCP IP.
When I use Centos7-based image (where network manager was not the default networking service) I dont have this issue.

cloud-init collect-logs output is attached.

Some more interesting outputs:
