      Given a system administrator is applying the current network state to a system with a gateway interface on a physical NIC,

      When they use nmstatectl to apply the current state configuration,

      Then, no link DOWN event should occur and the network state should be applied without causing any link flapping.

      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

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

      Do the same as https://issues.redhat.com/browse/RHEL-38607 , the fix  https://github.com/nmstate/nmstate/pull/2734 solved the original issue, but the link flaps when applying.

      This issue is for tracking flapping issue.

      Please provide the package NVR for which bug is seen:

      nmstate-2.2.34-0.20240709.2349git2bcabdf6.el9.x86_64
      NetworkManager-1.48.6-1.el9.x86_64

      How reproducible:

      Steps to reproduce

      1.  Reserve a (beaker) clean machine with the gateway interface set on a physical NIC
      2.  ip monitor link &> monitor.log 
      3.  nmstatectl show $gateway_nic | nmstatectl apply
      4.  cat monitor.log

      Expected results

      No link DOWN as I haven't change anything

      Actual results

      link DOWN and UP
