When moving interface ens1f0(slave interface) to down the REALTIME clock should move to FREERUN, as you can see in the logs it moves to FREERUN and back to LOCKED.

4.12.0-0.nightly-2022-10-25-210451

always

1.shutdown physical interface or interface on the switch
2. check the linux logs and event
3.see the clock realtime continues

CLOCK REALTIME is LOCKED  

CLOCK REALTIME should be FREERUN
