When Dual NIC is configured for ptp, only 1 should be configured with phc2sys; however ptplinux daemon logs shows phc2sys error when setting phc2sysOpts to empty string via ZTP.

Note that we cannot remove the phc2sysOps via ZTP due to limitations. So customer would need to manually edit the ptpconfig to remove phc2sysOpts post ZTP to work around this issue.

1. Deploy SNO DU node with Dual NIC ptp configs via ZTP (one NIC has phc2sysOpts set to "")

  spec:
    profile:
    - interface: ens5f0
      name: slave1
      phc2sysOpts: ""

2. Check ptp daemon logs
