From: Oleh Kuzhylnyi <[email protected]> [Why] The informative structure needs to be extended by the total number of DPPs required per each active plane. The new informative field is going to be used as a statistical indicator.
[How] The dml2_core_calcs_get_informative() routine must count a total number of DPPs.
