STRUCT IEEE80211_STA(9) Advanced driver interface STRUCT IEEE80211_STA(9)

NAME

struct_ieee80211_sta - station table entry

SYNOPSIS

struct ieee80211_sta {
  u32 supp_rates[IEEE80211_NUM_BANDS];
  u8 addr[ETH_ALEN];
  u16 aid;
  struct ieee80211_sta_ht_cap ht_cap;
  bool wme;
  u8 uapsd_queues;
  u8 max_sp;
  u8 drv_priv[0] __attribute__((__aligned__(sizeof(void  *))));
};

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 TX 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.
drv_priv[0] __attribute__((__aligned__(sizeof(void *))))
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.
