11   </p><p>
12
13   Rate control algorithms that agree to use the lowest rate to
14   send management frames and NO_ACK data with the respective hw
15   retries should use this in the beginning of their mac80211 get_rate
16   callback. If true is returned the rate control can simply return.
17   If false is returned we guarantee that sta and sta and priv_sta is
18   not null.
19   </p><p>
20
21   Rate control algorithms wishing to do more intelligent selection of
22   rate for multicast/broadcast frames may choose to not use this.
