Comment 4 Jan Safranek 2021-04-23 10:12:08 UTC 
`unknown-driver` is OK. It comes from the sidecars when it calls GetPluginInfo to get the driver name. The sidecar does not know name of the driver yet at that point. Therefore it's accounted as 'unknown-driver'. You could see also other calls with `unknown-driver`, such as Probe().
Comment 5 Wei Duan 2021-04-23 13:10:36 UTC 
Thanks, change the status to Verified.
