<h2>Changed behavior:</h2>

<li></li>
<li>DSR link layer notification has changed. The model originally used
"TxErrHeader" in Ptr<WifiMac> to indicate the transmission
error of a specific packet in link layer; however, it was not working
correctly. The model now uses a different path to implement
the link layer notification mechanism; specifically, looking into the
trace file to find packet receive events. If the model finds one
receive event for the data packet, it is used as the indicator for
successful data delivery.</li>
