 328  * ( REPLY_ADD_STA = 0x18 )
 329  * @add_modify: 1: modify existing, 0: add new station
 330  * @awake_acs:
 331  * @tid_disable_tx: is tid BIT(tid) enabled for Tx. Clear BIT(x) to enable
 332  *      AMPDU for tid x. Set %STA_MODIFY_TID_DISABLE_TX to change this field.
 333  * @mac_id_n_color: the Mac context this station belongs to
 334  * @addr[ETH_ALEN]: station's MAC address
 335  * @sta_id: index of station in uCode's station table
 336  * @modify_mask: STA_MODIFY_*, selects which parameters to modify vs. leave
 337  *      alone. 1 - modify, 0 - don't change.
 338  * @station_flags: look at %iwl_sta_flags
 339  * @station_flags_msk: what of %station_flags have changed
 340  * @add_immediate_ba_tid: tid for which to add block-ack support (Rx)
 341  *      Set %STA_MODIFY_ADD_BA_TID to use this field, and also set
 342  *      add_immediate_ba_ssn.
 343  * @remove_immediate_ba_tid: tid for which to remove block-ack support (Rx)
 344  *      Set %STA_MODIFY_REMOVE_BA_TID to use this field
 345  * @add_immediate_ba_ssn: ssn for the Rx block-ack session. Used together with
 346  *      add_immediate_ba_tid.
 347  * @sleep_tx_count: number of packets to transmit to station even though it is
 348  *      asleep. Used to synchronise PS-poll and u-APSD responses while ucode
 349  *      keeps track of STA sleep state.
 350  * @sleep_state_flags: Look at %iwl_sta_sleep_flag.
 351  * @assoc_id: assoc_id to be sent in VHT PLCP (9-bit), for grp use 0, for AP
 352  *      mac-addr.
 353  * @beamform_flags: beam forming controls
 354  * @tfd_queue_msk: tfd queues used by this station
 355  * @rx_ba_window: aggregation window size
 356  *
 357  * The device contains an internal table of per-station information, with info
 358  * on security keys, aggregation parameters, and Tx rates for initial Tx
 359  * attempt and any retries (set by REPLY_TX_LINK_QUALITY_CMD).
 360  *
 361  * ADD_STA sets up the table entry for one station, either creating a new
 362  * entry, or modifying a pre-existing one.
