1. NAME

ieee80211_find_sta_by_ifaddr - find a station on hardware

2. SYNOPSIS

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

3. ARGUMENTS

hw
    pointer as obtained from ieee80211_alloc_hw

addr
    remote stationAqs address

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

4. RETURN

The station, if found. NULL otherwise.

5. NOTE

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

6. NOTE

You may pass NULL for localaddr, but then you will just get the first STA that matches the remote address AqaddrAq. 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.
