rate_control_send_low - helper for drivers for management/no-ack frames
bool rate_control_send_low(struct ieee80211_sta * sta, void * priv_sta, struct ieee80211_tx_rate_control * txrc);
Rate control algorithms that agree to use the lowest rate to send management frames and NO_ACK data with the respective hw retries should use this in the beginning of their mac80211 get_rate callback. If true is returned the rate control can simply return. If false is returned we guarantee that sta and sta and priv_sta is not null.
Rate control algorithms wishing to do more intelligent selection of rate for multicast/broadcast frames may choose to not use this.
