<li> Minimum Ethernet packet size is 64 bytes</ul>
</dl>Invoke this function (through <a class="el" href="system_8h.html#a16">NETWORK_COMPLETE_SEND()</a> macro) when the whole packet is formed inside NIC's memory and is ready to be  sent. Proper length of the packet must be supplied so that NIC knows how much data to put on the line.
