MEMBERS

34       supp_rates[NUM_NL80211_BANDS]
35           Bitmap of supported rates (per band)
36
37       addr[ETH_ALEN]
38           MAC address
39
40       aid
41           AID we assigned to the station if we're an AP
42
43       ht_cap
44           HT capabilities of this STA; restricted to our own capabilities
45
46       vht_cap
47           VHT capabilities of this STA; restricted to our own capabilities
48
49       max_rx_aggregation_subframes
50           maximal amount of frames in a single AMPDU that this station is
51           allowed to transmit to us. Can be modified by driver.
52
53       wme
54           indicates whether the STA supports QoS/WME (if local devices does,
55           otherwise always false)
56
57       uapsd_queues
58           bitmap of queues configured for uapsd. Only valid if wme is
59           supported. The bits order is like in
60           IEEE80211_WMM_IE_STA_QOSINFO_AC_*.
61
62       max_sp
63           max Service Period. Only valid if wme is supported.
64
65       rx_nss
66           in HT/VHT, the maximum number of spatial streams the station can
67           receive at the moment, changed by operating mode notifications and
68           capabilities. The value is only valid after the station moves to
69           associated state.
70
71       bandwidth
72           current bandwidth the station can receive with
73
74       smps_mode
75           current SMPS mode (off, static or dynamic)
76
77       rates
78           rate control selection table
79
80       tdls
81           indicates whether the STA is a TDLS peer
82
83       tdls_initiator
84           indicates the STA is an initiator of the TDLS link. Only valid if
85           the STA is a TDLS peer in the first place.
86
87       mfp
88           indicates whether the STA uses management frame protection or not.
89
90       max_amsdu_subframes
91           indicates the maximal number of MSDUs in a single A-MSDU. Taken
92           from the Extended Capabilities element. 0 means unlimited.
93
94       support_p2p_ps
95           indicates whether the STA supports P2P PS mechanism or not.
96
97       max_rc_amsdu_len
98           Maximum A-MSDU size in bytes recommended by rate control.
99
100       txq[IEEE80211_NUM_TIDS]
101           per-TID data TX queues (if driver uses the TXQ abstraction)
102
103       drv_priv[0]
104           data area for driver use, will always be aligned to sizeof(void
105           \*), size is determined in hw information.
106

DESCRIPTION

108       A station table entry represents a station we are possibly
109       communicating with. Since stations are RCU-managed in mac80211, any
110       ieee80211_sta pointer you get access to must either be protected by
111       rcu_read_lock explicitly or implicitly, or you must take good care to
112       not use such a pointer after a call to your sta_remove callback that
113       removed it.
