  24 * enum ieee80211_sta_info_flags - Stations flags
  25 *
  26 * These flags are used with &struct sta_info's @flags member, but
  27 * only indirectly with set_sta_flag() and friends.
  28 *
  29 * @WLAN_STA_AUTH: Station is authenticated.
  30 * @WLAN_STA_ASSOC: Station is associated.
  31 * @WLAN_STA_PS_STA: Station is in power-save mode
  32 * @WLAN_STA_AUTHORIZED: Station is authorized to send/receive traffic.
  33 *	This bit is always checked so needs to be enabled for all stations
  34 *	when virtual port control is not in use.
  35 * @WLAN_STA_SHORT_PREAMBLE: Station is capable of receiving short-preamble
  36 *	frames.
  37 * @WLAN_STA_WDS: Station is one of our WDS peers.
  38 * @WLAN_STA_CLEAR_PS_FILT: Clear PS filter in hardware (using the
  39 *	IEEE80211_TX_CTL_CLEAR_PS_FILT control flag) when the next
  40 *	frame to this station is transmitted.
  41 * @WLAN_STA_MFP: Management frame protection is used with this STA.
  42 * @WLAN_STA_BLOCK_BA: Used to deny ADDBA requests (both TX and RX)
  43 *	during suspend/resume and station removal.
  44 * @WLAN_STA_PS_DRIVER: driver requires keeping this station in
  45 *	power-save mode logically to flush frames that might still
  46 *	be in the queues
  47 * @WLAN_STA_PSPOLL: Station sent PS-poll while driver was keeping
  48 *	station in power-save mode, reply when the driver unblocks.
  49 * @WLAN_STA_TDLS_PEER: Station is a TDLS peer.
  50 * @WLAN_STA_TDLS_PEER_AUTH: This TDLS peer is authorized to send direct
  51 *	packets. This means the link is enabled.
  52 * @WLAN_STA_TDLS_INITIATOR: We are the initiator of the TDLS link with this
  53 *	station.
  54 * @WLAN_STA_TDLS_CHAN_SWITCH: This TDLS peer supports TDLS channel-switching
  55 * @WLAN_STA_TDLS_OFF_CHANNEL: The local STA is currently off-channel with this
  56 *	TDLS peer
  57 * @WLAN_STA_TDLS_WIDER_BW: This TDLS peer supports working on a wider bw on
  58 *	the BSS base channel.
  59 * @WLAN_STA_UAPSD: Station requested unscheduled SP while driver was
  60 *	keeping station in power-save mode, reply when the driver
  61 *	unblocks the station.
  62 * @WLAN_STA_SP: Station is in a service period, so don't try to
  63 *	reply to other uAPSD trigger frames or PS-Poll.
  64 * @WLAN_STA_4ADDR_EVENT: 4-addr event was already sent for this frame.
  65 * @WLAN_STA_INSERTED: This station is inserted into the hash table.
  66 * @WLAN_STA_RATE_CONTROL: rate control was initialized for this station.
  67 * @WLAN_STA_TOFFSET_KNOWN: toffset calculated for this station is valid.
  68 * @WLAN_STA_MPSP_OWNER: local STA is owner of a mesh Peer Service Period.
  69 * @WLAN_STA_MPSP_RECIPIENT: local STA is recipient of a MPSP.
  70 * @WLAN_STA_PS_DELIVER: station woke up, but we're still blocking TX
  71 *	until pending frames are delivered
  72 * @WLAN_STA_USES_ENCRYPTION: This station was configured for encryption,
  73 *	so drop all packets without a key later.
  74 * @WLAN_STA_DECAP_OFFLOAD: This station uses rx decap offload
  75 *
  76 * @NUM_WLAN_STA_FLAGS: number of defined flags

 624 * struct sta_info - STA information
 625 *
 626 * This structure collects information about a station that
 627 * mac80211 is communicating with.
 628 *
 629 * @list: global linked list entry
 630 * @free_list: list entry for keeping track of stations to free
 631 * @hash_node: hash node for rhashtable
 632 * @addr: station's MAC address - duplicated from public part to
 633 *	let the hash table work with just a single cacheline
 634 * @local: pointer to the global information
 635 * @sdata: virtual interface this station belongs to
 636 * @ptk: peer keys negotiated with this station, if any
 637 * @ptk_idx: last installed peer key index
 638 * @rate_ctrl: rate control algorithm reference
 639 * @rate_ctrl_lock: spinlock used to protect rate control data
 640 *	(data inside the algorithm, so serializes calls there)
 641 * @rate_ctrl_priv: rate control private per-STA pointer
 642 * @lock: used for locking all fields that require locking, see comments
 643 *	in the header file.
 644 * @drv_deliver_wk: used for delivering frames after driver PS unblocking
 645 * @listen_interval: listen interval of this station, when we're acting as AP
 646 * @_flags: STA flags, see &enum ieee80211_sta_info_flags, do not use directly
 647 * @ps_lock: used for powersave (when mac80211 is the AP) related locking
 648 * @ps_tx_buf: buffers (per AC) of frames to transmit to this station
 649 *	when it leaves power saving state or polls
 650 * @tx_filtered: buffers (per AC) of frames we already tried to
 651 *	transmit but were filtered by hardware due to STA having
 652 *	entered power saving state, these are also delivered to
 653 *	the station when it leaves powersave or polls for frames
 654 * @driver_buffered_tids: bitmap of TIDs the driver has data buffered on
 655 * @txq_buffered_tids: bitmap of TIDs that mac80211 has txq data buffered on
 656 * @assoc_at: clock boottime (in ns) of last association
 657 * @last_connected: time (in seconds) when a station got connected
 658 * @last_seq_ctrl: last received seq/frag number from this STA (per TID
 659 *	plus one for non-QoS frames)
 660 * @tid_seq: per-TID sequence numbers for sending to this STA
 661 * @airtime: per-AC struct airtime_info describing airtime statistics for this
 662 *	station
 663 * @airtime_weight: station weight for airtime fairness calculation purposes
 664 * @ampdu_mlme: A-MPDU state machine state
 665 * @mesh: mesh STA information
 666 * @debugfs_dir: debug filesystem directory dentry
 667 * @dead: set to true when sta is unlinked
 668 * @removed: set to true when sta is being removed from sta_list
 669 * @uploaded: set to true when sta is uploaded to the driver
 670 * @sta: station information we share with the driver
 671 * @sta_state: duplicates information about station state (for debug)
 672 * @rcu_head: RCU head used for freeing this station struct
 673 * @reserved_tid: reserved TID (if any, otherwise IEEE80211_TID_UNRESERVED)
 674 * @amsdu_mesh_control: track the mesh A-MSDU format used by the peer:
 675 *
 676 *	  * -1: not yet known
 677 *	  * 0: non-mesh A-MSDU length field
 678 *	  * 1: big-endian mesh A-MSDU length field

 680 *
 681 * @fast_tx: TX fastpath information

 684 *	the BSS one.
 685 * @frags: fragment cache
 686 * @cur: storage for aggregation data
 687 *	&struct ieee80211_sta points either here or to deflink.agg.
 688 * @deflink: This is the default link STA information, for non MLO STA all link
 689 *	specific STA information is accessed through @deflink or through
 690 *	link[0] which points to address of @deflink. For MLO Link STA
 691 *	the first added link STA will point to deflink.
 692 * @link: reference to Link Sta entries. For Non MLO STA, except 1st link,
 693 *	i.e link[0] all links would be assigned to NULL by default and
 694 *	would access link information via @deflink or link[0]. For MLO
 695 *	STA, first link STA being added will point its link pointer to
 696 *	@deflink address and remaining would be allocated and the address
 697 *	would be assigned to link[link_id] where link_id is the id assigned
 698 *	by the AP.
 699 * @rem_link_stats: accumulated removed link stats
