Description of problem:
Metrics show slave interfaces as master when sync quality is low.
Version-Release number of selected component (if applicable):
ptp-operator.v4.16.0-202406200537
How reproducible:
100%
Steps to Reproduce:
1. Deploy 4.16 SNO with ptp-operator and BC/OC ptpconfigs
2. Check metrics for role and clock_state
Actual results:
ptpconfig boundary has two slave interfaces configured, ens1f3 and ens2f3:
[kni@registry.kni-qe-73 ~]$ oc get ptpconfigs.ptp.openshift.io -n openshift-ptp boundary -o yaml [...] spec: profile: - name: bc2 phc2sysOpts: "" ptp4lConf: | # The interface name is hardware-specific [ens2f3] masterOnly 0 [ens2f1] masterOnly 1 [ens2f2] masterOnly 1 [ens2f0] masterOnly 1 [...] - name: bc1 phc2sysOpts: "" ptp4lConf: | # The interface name is hardware-specific [ens1f3] masterOnly 0 [ens1f1] masterOnly 1 [ens1f2] masterOnly 1 [ens1f0] masterOnly 1
Metrics is showing these interfaces as master:
[kni@registry.kni-qe-73 ~]$ oc exec -it ds/linuxptp-daemon -n openshift-ptp -c linuxptp-daemon-container -- curl -s localhost:9091/metrics | grep role

No clock_state is shown for these interfaces.
If I change the clock_class_threshold from 135 to 248, the interfaces do show up as slaves and clock_state is reported:
[kni@registry.kni-qe-73 ~]$ oc get ptpconfigs.ptp.openshift.io -n openshift-ptp boundary -o yaml | grep -i threshold

Expected results:
Interfaces configured as slave should always show slave role in metrics.
