Interesting, but we do check:

drv_release_buffered_frames(struct ieee80211_local *local,
                            struct sta_info *sta, u16 tids, int num_frames,
                            enum ieee80211_frame_release_type reason,
                            bool more_data)
{
        trace_drv_release_buffered_frames(local, &sta->sta, tids, num_frames,
                                          reason, more_data);
        if (local->ops->release_buffered_frames)
                local->ops->release_buffered_frames(&local->hw, &sta->sta, tids,


So whatever you're trying to do must be something else.
