};

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)
rates
rate control selection table
tdls
indicates whether the STA is a TDLS peer
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.
