The configuration data should only store the static configuration data and not dynamic data. In addition, storing HT configuration and state in IEs is not the easiest way of doing this, so use more convenient data types for storing configuration and dynamic state. The HT IEs are then generated based on the static configuration and dynamic state whenever needed.
