   These flags are used with the <code class="function">ampdu_action</code> callback in
   <span class="structname">struct ieee80211_ops</span> to indicate which action is needed.
   </p><p>

   Note that drivers MUST be able to deal with a TX aggregation
   session being stopped even before they OK'ed starting it by
   calling ieee80211_start_tx_ba_cb_irqsafe, because the peer
   might receive the addBA frame and send a delBA right away!
