The current ieee80211_tx_info.rate_driver_data overlaps with some of the non-rate data (e.g. ampdu_ack_len), so it might not be good enough. Since we already know how much free bytes remained, simply use this size to define (void *) array. While on it, change ack_signal type from int to the more explicit s32 type.
