- * NOTE: This function should not be used! When mac80211 is converted

- * BSSID on the same AP hardware without disconnecting first).
+ * 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.
