For some frames c->control.rates[0].idx is negative, which means ieee80211_get_tx_rate() will print a warning and return NULL. Only management frames have USE_DRIVER_RATE set, so for all others the rate info of txdesc is ignored anyway. Remove call to ieee80211_get_tx_rate() and send management frames with 1M (rate info = 0).
