- * @file strategy_dpo_ctx.h
- *
- * This file implements the general hICN DPO ctx (shared among all the strategies).
- *
- * An hICN DPO ctx contains the list of next hops, auxiliaries fields to maintain the dpo, map-me
- * specifics (tfib_entry_count and seq), the dpo_type and 64B to let each strategy to store additional
- * information. Each next hop is an hicn_face_id_t that refers to an index for an hICN face. The
- * dpo_type is used to identify the strategy and to retrieve the vft corresponding to the strategy
- * (see strategy.h) and to the dpo ctx (see strategy_dpo_manager.h)
