Hi,

this series does basically two things:

1. Disables automatic load balancing as adviced by the hardware
   workaround.

2. Forces the sharing of the load submitted to CCS among all the
   CCS available (as of now only DG2 has more than one CCS). This
   way the user, when sending a query, will see only one CCS
   available.
