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.
