Can we add a testcase where "ptp: enabled" is not defined but uplinksis defined.

[laxmikantchintakindi]

ptp_settings in PTP_TESTS.yml group vars is set to true. So even ptp:enabled is not set, there will be no change in configs.

[Vibhu-gslab]

I understand, but having a testcase for it would make it more clear.
You can mention in comment above testcase what it is for.

[MaheshGSLAB]

Can you add more tests like uplinks under defaults and node group

[laxmikantchintakindi]

Addressed both comments.
