Yes, that would be ok for now. By the way, you don't have to calculate
the ampdu length before sending out the first tx status event.
You could send out the tx status of everything but the last frame with
IEEE80211_TX_CTL_AMPDU set and IEEE80211_TX_STAT_AMPDU unset.
Then on the last frame, set IEEE80211_TX_STAT_AMPDU in the info, and add
the proper ampdu length.
minstrel_ht does not care in which order the tx status events for a
single ampdu arrive, because it ignores every status report where
IEEE80211_TX_CTL_AMPDU is set and IEEE80211_TX_STAT_AMPDU is not.
