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 QoS/WME.

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)

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.

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.
