1. Proposed title of this feature request
Include NetworkManager-config-server package into RHCOS

2. What is the nature and description of the request?
Ask is to include the package `NetworkManager-config-server` into RHCOS so that RHCOS behaves like RHEL with regards to `ignore-carrier`per default in RHEL

3. Why does the customer need this? (List the business requirements here)
Depending on how a cluster is configured during install via RHACM it creates even for unused interfaces NetworkManager files. Now, if those interfaces (physical functions) are used later on with SRIOV, which creates the virtual functions, the MTU in SRIOV may differ from the initially configured MTU and SRIOV changes the MTU even for the PF. In case the link to the PF is lost, Networkmanager resets the MTU to the default while SRIOV sets it then back to its configured MTU which leads to the VF interfaces getting removed, also from the assigned pod.
In RHEL `NetworkManager-config-server` package is used to set `ignore-carrier` to avoid that, however it is not present in RHCOS
Mind there is a long discussion about this with SRIOV and NetworkManager engineering in https://issues.redhat.com/browse/RHEL-88643

4. List any affected packages or components.
