IEEE80211_TX_CTL_AMPDU was set by mac80211 for aggregation pkt. But when iwlwifi receive the tx status reply, it reset the flag to following info->flags = IEEE80211_TX_STAT_ACK; info->flags |= IEEE80211_TX_STAT_AMPDU; it causes the rate-scaling to not work for aggregation pkt if we checking for IEEE80211_TX_CTL_AMPDU flag.
