the loop back user core issue

[ducdracaena]

I want to build a 100G tcp/ip server in fpga, so pc client can send data to server and server can loop back that data to pc client. I have changed the ipert core but that core is only receive. Could you please take a look at that code and let me know where is issue?

switch (serverFsmState)
{
case WAIT_PKG:
	if (!rxMetaData.empty() && !rxDataBuffer.empty())
	{
		rxMetaData.read();
		net_axis<WIDTH> receiveWord = rxDataBuffer.read();
		if (!receiveWord.last)
		{
			serverFsmState = CONSUME;
		}
	}
	break;
case CONSUME:
	if (!rxDataBuffer.empty())
	{
		receiveWord = rxDataBuffer.read();
		if (receiveWord.last)
		{
			serverFsmState = WRITE_PKG;
		}
	}
	break;
case WRITE_PKG:
{
	txDataBuffer.write(receiveWord);
	if (receiveWord.last)
	{
		serverFsmState = WAIT_PKG;
	}
}
	break;
}

Thank you, Duc
