Boba, don't forget to check other parts of FW filter - the ID, bootstraps, previous version, etc. That things could make the difference.

Is some one have 211k ? Could you post System Info to help distinguish it ?

PS. BTW, that posted info related to "DP411" as internal name picked from FW, not by marketing assignment.
Seems to me the internal model name from streaming data finally make a match to the "211k" name.
