Description Federico Paolinelli 2020-10-29 14:19:17 UTC 
Description of problem:

It happened sporadically in our CI, but what I am seeing is a vf sneaking in the list of devices in the nodeptpdevice CRD.




How reproducible:
Flaky

Actual results:


Expected results:


Additional info:

Looking at the code, the ptp daemon loops and always fetches the list of devices and appends new ones, so I suspect there's a race if the daemon checks for the devices when the vfs are getting created (maybe the link is already created, but not the physfn link?).

Once this happens, the device is never removed from the list because of the append mechanism.
