  *
- * NOTE: This function should not be used! When mac80211 is converted
- *	 internally to properly keep track of stations on multiple
- *	 virtual interfaces, it will not always know which station to
- *	 return here since a single address might be used by multiple
- *	 logical stations (e.g. consider a station connecting to another
- *	 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.
+ * DO NOT USE THIS FUNCTION with localaddr NULL if at all possible.
