It seems like Onoe fails as well.  I have traced down to the following source
of problems:

src/devices/wifi/minstrel-wifi-manager.cc

bool
MinstrelWifiManager::IsLowLatency (void) const
{
  return false;
}

and  

src/devices/wifi/wifi-remote-station-manager.cc:353

 if (!IsLowLatency ())
    {
      // Note: removing the packet below is wrong: what happens in case of
retransmissions ???
      TxModeTag tag;
      bool found;
      found = ConstCast<Packet> (packet)->RemovePacketTag (tag);
      NS_ASSERT (found);
      return tag.GetDataMode ();
    }

I still don't understand how we are modeling the LowLantency and not low
latency(e.g. removing TxModeTag)
