IEEE80211_FIND_STA_B(9)             Advanced driver interface             IEEE80211_FIND_STA_B(9)



NAME
       ieee80211_find_sta_by_ifaddr - find a station on hardware

SYNOPSIS
       struct ieee80211_sta * ieee80211_find_sta_by_ifaddr(struct ieee80211_hw * hw,
                                                           const u8 * addr,
                                                           const u8 * localaddr);

ARGUMENTS
       hw
           pointer as obtained from ieee80211_alloc_hw

       addr
           remote station's address

       localaddr
           local address (vif->sdata->vif.addr). Use NULL for 'any'.

RETURN
       The station, if found.  NULL otherwise.

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

NOTE
       You may pass NULL for localaddr, but then you will just get the first STA that matches the
       remote address 'addr'. We can have multiple STA associated with multiple logical stations
       (e.g. consider a station connecting to another BSSID on the same AP hardware without
       disconnecting first). In this case, the result of this method with localaddr NULL is not
       reliable.

       DO NOT USE THIS FUNCTION with localaddr NULL if at all possible.
