Given a network interface with a configured speed of 1000 Mbps and no pending changes,

When the system administrator runs nmstatectl show <interface> | nmstatectl apply on that interface,

Then nmstate completes without triggering a link DOWN/UP event or rollback due to a verification error on ethernet.speed.

Definition of Done:

The implementation meets the acceptance criteria

The fix is part of a downstream build attached to an errata

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

The link flapping issue of applying mp-tcp (https://issues.redhat.com/browse/RHEL-53211 ) has been fixed in https://github.com/nmstate/nmstate/pull/2833 , but running the reproducer can still observe the link down/up, which is caused by rollback on verification failure of ethernet.speed

Tested on beaker machines

dell-per740-80.rhts.eng.pek2.redhat.com

dell-per740-86.rhts.eng.pek2.redhat.com

What is the impact of this issue to you?

Link down/up, this will cause the network traffic loss

Please provide the package NVR for which the bug is seen:

nmstate-2.2.40-0.20250120.2444git2133c4ba.el9.x86_64
NetworkManager-1.51.5-1.el9.x86_64

How reproducible is this bug?:

100%

Steps to reproduce

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

Expected results

No link DOWN as there is nothing changed in the desired state

Actual results

link DOWN and then UP
