 * @active_nic_arc: This field contains a bit per ARC of the NIC engines.
 *                  Once an engine arc is initialized, its respective bit is
 *                  set. Each respective bit is cleared upon reset of its
 *                  corresponding ARC of the NIC engine.
 * @hw_events: array that holds all H/W events that are defined valid.
 * @events_stat: array that holds histogram of all received events.
 * @events_stat_aggregate: same as events_stat but doesn't get cleared on reset.
 * @num_of_valid_hw_events: used to hold the number of valid H/W events.
 * @nic_ports: array that holds all NIC ports manage structures.
 * @nic_macros: array that holds all NIC macro manage structures.
 * @core_info: core info to be used by the Ethernet driver.
 * @aux_ops: functions for core <-> aux drivers communication.
 * @flush_db_fifo: flag to force flush DB FIFO after a write.
 * @hbm_cfg: HBM subsystem settings
 * @hw_queues_lock_mutex: used by simulator instead of hw_queues_lock.
 * @kdma_lock_mutex: used by simulator instead of kdma_lock.
 * @use_deprecated_event_mappings: use old event mappings which are about to be
 *                                 deprecated
