      Description of problem:

      Some of the recommended PTP parameters for ordinary and boundary clock do not match the values included in https://github.com/openshift-kni/cnf-features-deploy/blob/release-4.12/ztp/source-crs/PtpConfigSlave.yaml and https://github.com/openshift-kni/cnf-features-deploy/blob/release-4.12/ztp/source-crs/PtpConfigBoundary.yaml, causing confusion to customers and partners on what are the parameters they should use.

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

      Seen at least in the OCP 4.12 and 4.13 documentation

      How reproducible:

      Always

      Steps to Reproduce:

      1. Compare the "Recommended PTP ordinary clock configuration" and "Recommended PTP boundary clock configuration" from the documentation at https://docs.openshift.com/container-platform/4.12/networking/using-ptp.html#configuring-linuxptp-services-as-boundary-clock_using-ptp with the corresponding values in the https://github.com/openshift-kni/cnf-features-deploy/blob/release-4.12/ztp/source-crs repository
      

      Actual results:

      The following ptp4lConf values are different:
      
      30c31
      <   fault_reset_interval 4    (this is in the documentation)
      ---
      >   fault_reset_interval -4   (this is the repo)
      53a55
      >   clock_class_threshold 7   (this parameter is present in the repo and missing in the documentation)
      

      Expected results:

      Same recommended values in both places for consistency.
