NAME

6       ieee80211_find_sta_by_ifaddr - find a station on hardware
7

SYNOPSIS

9       struct ieee80211_sta *
10                                                           ieee80211_find_sta_by_ifaddr(struct ieee80211_hw * hw,
11                                                           const u8 * addr,
12                                                           const u8 * localaddr);
13

ARGUMENTS

15       hw
16           pointer as obtained from ieee80211_alloc_hw
17
18       addr
19           remote station's address
20
21       localaddr
22           local address (vif->sdata->vif.addr). Use NULL for 'any'.
23

RETURN

25       The station, if found.  NULL otherwise.
26

NOTE

28       This function must be called under RCU lock and the resulting pointer
29       is only valid under RCU lock as well.
30

NOTE

32       You may pass NULL for localaddr, but then you will just get the first
33       STA that matches the remote address 'addr'. We can have multiple STA
34       associated with multiple logical stations (e.g. consider a station
35       connecting to another BSSID on the same AP hardware without
36       disconnecting first). In this case, the result of this method with
37       localaddr NULL is not reliable.
38
39       DO NOT USE THIS FUNCTION with localaddr NULL if at all possible.
