      This is a clone of issue OCPBUGS-36496. The following is the description of the original issue:

      Description of problem:

          GM clock_state is stuck in freerun with very hugh ts2phc offsets

      Version-Release number of selected component (if applicable):

          ptp-operator.v4.15.0-202407021637

      How reproducible:

          100%

      Steps to Reproduce:

          1. Deploy 4.15 SNO with GM ptpconfig
    2. Check metrics for clock_state
    3. Check linuxptp-daemon log for ts2phc offset

      Actual results:

      ptpconfigs:

      NAMESPACE       NAME               AGE
openshift-ptp   du-ptp-slave-gm1   42m
openshift-ptp   du-ptp-slave-gm2   42m
openshift-ptp   grandmaster1       42m

      GM clock_state is reported as freerun in metrics:

      [kni@registry.kni-qe-61 ~]$ oc exec -it ds/linuxptp-daemon  -n openshift-ptp -c linuxptp-daemon-container -- curl -s localhost:9091/metrics | grep clock_state
# HELP openshift_ptp_clock_state 0 = FREERUN, 1 = LOCKED, 2 = HOLDOVER
# TYPE openshift_ptp_clock_state gauge

openshift_ptp_clock_state{iface="ens7fx",node="helix60.lab.eng.rdu2.redhat.com",process="ts2phc"} 1

      ts2phc offsets are very high in linuxptp-daemon log:

      ts2phc[4116.338]: [ts2phc.2.config] ens7f0 extts index 0 at 1720011075.040044361 corr 0 src 1720011074.482098424 diff 1040044361
ts2phc[4116.338]: [ts2phc.2.config] ens7f0 master offset 1040044361 s2 freq +900000000

      Expected results:

      GM clock_state reporting as locked and normal ts2phc offsets
