From: Parav Pandit <parav@nvidia.com>

In the current code, the current and maximal capabilities are
maintained in separate arrays which are both per type. In order to
allow the creation of such a basic structure as a dynamically
allocated array, we move curr and max fields to a unified
structure so that specific capabilities can be allocated as one unit.
