IEEE80211_FIND_STA(9) Advanced driver interface IEEE80211_FIND_STA(9)NAME
ieee80211_find_sta - find a station
struct ieee80211_sta * ieee80211_find_sta(struct ieee80211_vif * vif, const u8 * addr);
virtual interface to look for station on
The station, if found. NULL otherwise.
This function must be called under RCU lock and the resulting pointer is only valid under RCU lock as well.

IEEE80211_GET_BUFFER(9) Advanced driver interface IEEE80211_GET_BUFFER(9)NAME
ieee80211_get_buffered_bc - accessing buffered broadcast and multicast frames
struct sk_buff * ieee80211_get_buffered_bc(struct ieee80211_hw * hw, struct ieee80211_vif * vif);
pointer as obtained from ieee80211_alloc_hw.
struct ieee80211_vif pointer from the add_interface callback.
Function for accessing buffered broadcast and multicast frames. If hardware/firmware does not implement buffering of broadcast/multicast
frames when power saving is used, 802.11 code buffers them in the host memory. The low-level driver uses this function to fetch next
buffered frame. In most cases, this is used when generating beacon frame.
A pointer to the next buffered skb or NULL if no more buffered frames are available.
buffered frames are returned only after DTIM beacon frame was generated with ieee80211_beacon_get and the low-level driver must thus call
ieee80211_beacon_get first. ieee80211_get_buffered_bc returns NULL if the previous generated beacon was not DTIM, so the low-level driver
does not need to check for DTIM beacons separately and should be able to use common code for all beacons.
