       struct ieee80211_sta {
	 u32 supp_rates[IEEE80211_NUM_BANDS];
	 u8 addr[ETH_ALEN];
	 u16 aid;

	 struct ieee80211_sta_vht_cap vht_cap;
	 bool wme;
	 u8 uapsd_queues;
	 u8 max_sp;
	 u8 rx_nss;
	 enum ieee80211_sta_rx_bandwidth bandwidth;
	 enum ieee80211_smps_mode smps_mode;
	 u8 drv_priv[0];
       };

MEMBERS

       supp_rates[IEEE80211_NUM_BANDS]
	   Bitmap of supported rates (per band)

       addr[ETH_ALEN]
	   MAC address

       aid
	   AID we assigned to the station if we're an AP

       ht_cap
	   HT capabilities of this STA; restricted to our own capabilities

       vht_cap
	   VHT capabilities of this STA; restricted to our own capabilities

       wme
	   indicates whether the STA supports WME. Only valid during AP-mode.

       uapsd_queues
	   bitmap of queues configured for uapsd. Only valid if wme is supported.

       max_sp
	   max Service Period. Only valid if wme is supported.

       rx_nss
	   in HT/VHT, the maximum number of spatial streams the station can receive at the moment, changed by operating mode notifications and
	   capabilities. The value is only valid after the station moves to associated state.

       bandwidth
	   current bandwidth the station can receive with

       smps_mode
	   current SMPS mode (off, static or dynamic)

       drv_priv[0]
	   data area for driver use, will always be aligned to sizeof(void *), size is determined in hw information.

DESCRIPTION

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