There was a problem hiding this comment.
I would suggest to add an "else" - if this file doesn't exist for some reason, try to check the under-sku file.
Need to think if we want to have this approach -
on the one hand it may cause the bug to appear again. on the second hand, it is under /tmp/ folder and might be deleted. we want to continue the flow even if file was deleted from inside the docker.

Why I did it
Two steps are required to enable the host CMIS management feature: enabling it in the switch's sai.profile and performing a config reload. During the timeframe between these two steps, the control sysfs might be accessed, but they will not be present on the system until the latter step, the config reload, is completed. The code should try to access the control sysfs only after the config reload step. A good indication that this has been done is to check if the relevant entry is included in syncd's sai.profile. In contrast to the switch's sai.profile, syncd's sai.profile is only updated with the Host CMIS management support flag after the reload is complete.

How I did it
I updated the is_module_host_management_mode() implementation to first look for the Host CMIS management support flag in syncd's sai.profile, and only if it does not exist for some reason, look for it in the switch's sai.profile.
How to verify it
Add the Host CMIS management support flag to the switch's sai.profile and verify that the following log does not appear:
ERR pmon#xcvrd: Exception occured at DomInfoUpdateTask thread due to Exception('control sysfs for SFP 20 does not exist')
