ptp4l process restarted unexpected with dual NIC boundary clocks configured

ptp4l process restarted unexpected with dual NIC boundary clocks configured

4.12.z, may exist in other version as well like 4.13.z and 4.14

Always, but may need to wait for hours 

1. Enable dual NIC boundary clocks on a SNO cluster
2. Check linuxptp-daemon pod logs(linuxptp-daemon-container) 

Seeing the ptp4l process restarted unexpectedly

ptp4l process should not be restarted if there is no ptpconfig changes
