This seems similar to normal SR-IOV operation, but I've not heard of
use cases for them VM to know what its pvid is. Could you elaborate?  

It's provided for informational purposes.

Seems like an information leak :S and since it's equivalent to the
standard SR-IOV functionality - we'd strongly prefer a common
interface for all use cases. sysfs won't be it. Jiri & Mellanox had 
been working on something in devlink for quite some time.

Agreed, Thomas please work with Jiri et al. so that you can provide
this information using a standard facility.

Thanks.
