can we read the module advertised datapath init time and use it so that we have it working for both ZR and non-ZR without hardcoding this here?

To read CMIS dp state duration, I create another PR in sonic-platform-common (sonic-net/sonic-platform-common#312).

@abohanyang - How is #312 (above) different from #290 ?
Looks same

Hi @shyam77git , it's to address the same issue. but some of my code changes (sonic-net/sonic-platform-common#312 ) are in a different repo. I think we need a separate PR for that part.

Hi @abohanyang
Is #312 sufficient to take care of what's mentioned in #290 or anything more required?
Note that #294 to take care for xcvrd side changes.

No. 312 contains the implementation of API, get_datapath_init_duration. I just commit more changes in this PR.

Thanks for the clarification.
This PR now is going to take care of git issue #293 - I'm reviewing this further

@abohanyang : get_cmis_expired() - is this a temporary function defined to validate this fix - #293?

practically, get_datapath_init_duration() and get_datapath_deinit_duration() to be invoked instead.
Would you be taking care of this as part of this PR? or shall we take care of this in xcvrd.py via git issue #294 ?

Yes. I just commit more changes in this PR to call get_datapath_init_duration and get the expiration time.

OK.
@abohanyang : can you please attach UT cases, logs for this case (400G ZR optics FSM working via xcrd.py as orchestrator with these timeouts all the way to interface in 'operational up' state)
