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.
