<h2>Changes to existing API:</h2>
<ul>
<li> Class <b>LrWpanMac</b> now supports extended addressing mode. Both <b>McpsDataRequest</b> and <b>PdDataIndication</b> methods will now use extended addressing if <b>McpsDataRequestParams::m_srcAddrMode</b> or <b>McpsDataRequestParams::m_dstAddrMode</b> are set to <b>EXT_ADDR</b>.
