Can be modified by driver. ``wme`` indicates whether the STA supports QoS/WME (if local devices does, otherwise always false) ``uapsd_queues`` bitmap of queues configured for uapsd. Only valid if wme is supported. The bits order is like in IEEE80211_WMM_IE_STA_QOSINFO_AC_*. ``max_sp`` max Service Period. Only valid if wme is supported. ``rates`` rate control selection table ``tdls`` indicates whether the STA is a TDLS peer ``tdls_initiator`` indicates the STA is an initiator of the TDLS link. Only valid if the STA is a TDLS peer in the first place. ``mfp`` indicates whether the STA uses management frame protection or not. ``mlo`` indicates whether the STA is MLO station. ``spp_amsdu`` indicates whether the STA uses SPP A-MSDU or not. ``max_amsdu_subframes`` indicates the maximal number of MSDUs in a single A-MSDU. Taken from the Extended Capabilities element. 0 means unlimited. ``eml_cap`` EML capabilities of this MLO station ``cur`` currently valid data as aggregated from the active links For non MLO STA it will point to the deflink data. For MLO STA ieee80211_sta_recalc_aggregates() must be called to update it. ``support_p2p_ps`` indicates whether the STA supports P2P PS mechanism or not. ``txq`` per-TID data TX queues; note that the last entry (``IEEE80211_NUM_TIDS``) is used for non-data frames ``valid_links`` bitmap of valid links, or 0 for non-MLO ``ext_mld_capa_ops`` the MLD's extended MLD capabilities and operations ``epp_peer`` indicates that the peer is an EPP peer. ``deflink`` This holds the default link STA information, for non MLO STA all link specific STA information is accessed through **deflink** or through link[0] which points to address of **deflink**. For MLO Link STA the first added link STA will point to deflink. ``link`` reference to Link Sta entries. For Non MLO STA, except 1st link, i.e link[0] all links would be assigned to NULL by default and would access link information via **deflink** or link[0]. For MLO STA, first link STA being added will point its link pointer to **deflink** address and remaining would be allocated and the address would be assigned to link[link_id] where link_id is the id assigned by the AP. ``nmi`` For NDI stations, pointer to the NMI station of the peer. ``nan_sched`` NAN peer schedule for this station. Valid only for NMI stations. ``drv_priv`` data area for driver use, will always be aligned to sizeof(void \*), size is determined in hw information.h](h)}(h**Definition**::h](j)}(h**Definition**h]h Definition}(hjGhhhNhNubah}(h]h ]h"]h$]h&]uh1jhjGubh:}(hjGhhhNhNubeh}(h]h ]h"]h$]h&]uh1hhj/var/lib/git/docbuild/linux/Documentation/driver-api/80211/mac80211-advanced:113: ./include/net/mac80211.hhMr hjGubj)}(hXstruct ieee80211_sta { u8 addr[ETH_ALEN]; u16 aid; u16 max_rx_aggregation_subframes; bool wme; u8 uapsd_queues; u8 max_sp; struct ieee80211_sta_rates *rates; bool tdls; bool tdls_initiator; bool mfp; bool mlo; bool spp_amsdu; u8 max_amsdu_subframes; u16 eml_cap; struct ieee80211_sta_aggregates *cur; bool support_p2p_ps; struct ieee80211_txq *txq[IEEE80211_NUM_TIDS + 1]; u16 valid_links; u16 ext_mld_capa_ops; bool epp_peer; struct ieee80211_link_sta deflink; struct ieee80211_link_sta *link[IEEE80211_MLD_MAX_NUM_LINKS]; struct ieee80211_sta *nmi; struct ieee80211_nan_peer_sched *nan_sched; u8 drv_priv[]; };h]hXstruct ieee80211_sta { u8 addr[ETH_ALEN]; u16 aid; u16 max_rx_aggregation_subframes; bool wme; u8 uapsd_queues; u8 max_sp; struct ieee80211_sta_rates *rates; bool tdls; bool tdls_initiator; bool mfp; bool mlo; bool spp_amsdu; u8 max_amsdu_subframes; u16 eml_cap; struct ieee80211_sta_aggregates *cur; bool support_p2p_ps; struct ieee80211_txq *txq[IEEE80211_NUM_TIDS + 1]; u16 valid_links; u16 ext_mld_capa_ops; bool epp_peer; struct ieee80211_link_sta deflink; struct ieee80211_link_sta *link[IEEE80211_MLD_MAX_NUM_LINKS]; struct ieee80211_sta *nmi; struct ieee80211_nan_peer_sched *nan_sched; u8 drv_priv[]; };}hj Hsbah}(h]h ]h"]h$]h&]j]j^uh1jhj/var/lib/git/docbuild/linux/Documentation/driver-api/80211/mac80211-advanced:113: ./include/net/mac80211.hhMt hjGubh)}(h **Members**h]j)}(hjHh]hMembers}(hjHhhhNhNubah}(h]h ]h"]h$]h&]uh1jhjHubah}(h]h ]h"]h$]h&]uh1hhj/var/lib/git/docbuild/linux/Documentation/driver-api/80211/mac80211-advanced:113: ./include/net/mac80211.hhM hjGubj)}(hhh](j)}(h``addr`` MAC address h](j)}(h``addr``h]j)}(hjHhhhNhNubah}(h]h ]h"]h$]h&]uh1jhj:Hubah}(h]h ]h"]h$]h&]uh1jhj/var/lib/git/docbuild/linux/Documentation/driver-api/80211/mac80211-advanced:113: ./include/net/mac80211.hhMz hj6Hubj)}(hhh]h)}(h MAC addressh]h MAC address}(hjUHhhhNhNubah}(h]h ]h"]h$]h&]uh1hhjQHhMz hjRHubah}(h]h ]h"]h$]h&]uh1jhj6Hubeh}(h]h ]h"]h$]h&]uh1jhjQHhMz hj3Hubj)}(h6``aid`` AID we assigned to the station if we're an AP h](j)}(h``aid``h]j)}(hjuHh]haid}(hjwHhhhNhNubah}(h]h ]h"]h$]h&]uh1jhjsHubah}(h]h ]h"]h$]h&]uh1jhj/var/lib/git/docbuild/linux/Documentation/driver-api/80211/mac80211-advanced:113: ./include/net/mac80211.hhM{ hjoHubj)}(hhh]h)}(h-AID we assigned to the station if we're an APh]h/AID we assigned to the station if we’re an AP}(hjHhhhNhNubah}(h]h ]h"]h$]h&]uh1hhjHhM{ hjHubah}(h]h ]h"]h$]h&]uh1jhjoHubeh}(h]h ]h"]h$]h&]uh1jhjHhM{ hj3Hubj)}(h``max_rx_aggregation_subframes`` maximal amount of frames in a single AMPDU that this station is allowed to transmit to us.

spinlock used to protect rate control data (data inside the algorithm, so serializes calls there) ``lock`` used for locking all fields that require locking, see comments in the header file.

listen interval of this station, when we're acting as AP ``dead`` set to true when sta is unlinked ``removed`` set to true when sta is being removed from sta_list ``uploaded`` set to true when sta is
