 *	see &enum iwl_ctxt_id_and_color
 * @addr: station's MAC address
 * @reserved2: reserved
 * @sta_id: index of station in uCode's station table
 * @modify_mask: from &enum iwl_sta_modify_flag, selects what to change
 * @reserved3: reserved
 * @station_flags: look at &enum iwl_sta_flags
 * @station_flags_msk: what of %station_flags have changed,
 *	also &enum iwl_sta_flags
 * @add_immediate_ba_tid: tid for which to add block-ack support (Rx)
 *	Set %STA_MODIFY_ADD_BA_TID to use this field, and also set
 *	add_immediate_ba_ssn.
 * @remove_immediate_ba_tid: tid for which to remove block-ack support (Rx)
 *	Set %STA_MODIFY_REMOVE_BA_TID to use this field
 * @add_immediate_ba_ssn: ssn for the Rx block-ack session. Used together with
 *	add_immediate_ba_tid.
 * @sleep_tx_count: number of packets to transmit to station even though it is
 *	asleep. Used to synchronise PS-poll and u-APSD responses while ucode
 *	keeps track of STA sleep state.
 * @station_type: type of this station. See &enum iwl_sta_type.
 * @sleep_state_flags: Look at &enum iwl_sta_sleep_flag.
 * @assoc_id: assoc_id to be sent in VHT PLCP (9-bit), for grp use 0, for AP
 *	mac-addr.
 * @beamform_flags: beam forming controls
 * @tfd_queue_msk: tfd queues used by this station.
 *	Obselete for new TX API (9 and above).
 * @rx_ba_window: aggregation window size
 * @sp_length: the size of the SP in actual number of frames
 * @uapsd_acs:  4 LS bits are trigger enabled ACs, 4 MS bits are the deliver
 *	enabled ACs.
 *
 * The device contains an internal table of per-station information, with info
 * on security keys, aggregation parameters, and Tx rates for initial Tx
 * attempt and any retries (set by REPLY_TX_LINK_QUALITY_CMD).
 *
 * ADD_STA sets up the table entry for one station, either creating a new
 * entry, or modifying a pre-existing one.
