 class SfpUtil(SfpUtilBase):


Please use Sfp refactoring because SFP handling in SONiC has moved to mostly platform independent code. Ref: SFP refactoring HLD.

Use SfpOptoeBase class instead of SfpUtilBase (which is going to be phased out)

Example Dell platform moved to using SFP refactored code : - #9016

@prgeor , thank you for reviewing. Totally make sense. Looks like redesigning into sonic_xcvr approach and testing will take some time. Can we have these changes merged as-is (mainly because of other components) and refactor SFP part in a separate PR?

sonic_xcvr is already tested so your platform is good to use sonic_xcvr approach. There is very little code that is platform specific when it comes to supporting the transceivers, so very less platform specific code means less testing and bugs for your platform. please let me know if you face any issue while moving to sonic_xcvr.

akokhan · 2022-01-14T08:50:58Z

@prgeor , thank you for reviewing the changes.

As you can see, in this SFP plugin we expose SFP eeprom content through the file cache which is updated each time get_eeprom_path() is executed. Some APIs we still implement explicitly through SDK platform calls. Mostly to improve performance. Also, since eeprom is emulated through the file cache, we override write_eeprom() to disable write access which does not make sense in this case. Instead, whenever is needed, we implement write APIs explicitly. E.g., tx_disable(), tx_disable_channel(). The implementation can be extended and/or improved in the future.

In future when your platform needs to support QSFP-DD then your platform will have to duplicate the code in sonic_xcvr. Currently Xcvrd only collects DOM related info from transceiver, but in future QSFP-DD module will need initialization which has data path link synchronization requirement see ref. sonic-net/SONiC#916. Xcvrd is platform independent and won't support any platform specific requirement and hence its important for platform to re-use sonic_xcvr which is compliant with various MSA specifications.

akokhan · 2022-01-17T07:11:01Z

@prgeor , thank you for the detailed explanation. I really appreciate this. We will plan and adjust SFP plugin implementation accordingly.
