Vodafone Stations / devices that doesn't expose DOCSIS errors

Deployment Method

Bug Description

Vodafone Stations don't give info about DOCSIS errors, but DOCSight dashboard shows "0.0% errors, status: good" in green, when in fact the DOCSIS error status is unkown.
This gives the false impression that the feature is supported, there are no errors and everything is ok.

Steps to Reproduce

1. Go to Dashboard
2. ERRORS-tile shows wrong DOCSIS error data

Expected Behavior

If the device doesn't support it, the error tile should give a clear message/warning like "unsupported" or be hidden.
