===============================================================
Changlog
	2014-03-18 Done.
	2014-05-09 Version 0.1.0
			   + Read the configure file instead of reading 
				 the paras from command line.
			   + Reorganize the source structure for the MESA
			     standard.
			   + New Makefile to replace the buildso.sh
			   + Other improvement.
	2014-05-13 Version 0.1.1
			   + Add the test application source and header file
				 to path ./test
	2014-05-13 Version 0.1.2
			   + Fix some bugs in Makefile, and we don't need to
			     link a lot of libs while complete with our .so 
			     file.
	2014-07-03 Version 0.2.0
			   + Add the module APT,which to adapt the run envoriment by itself,
			     now can support the EAL paras.
	2014-12-11 Version 1.1.0
			   + Support Multiprocess Mode and Complete Load-Balance Model.

Interface and Paras.
=====================

We provide two kinds of interface. One of them provide the stream id for users,and the other provide the
port number in physical.

**Note**   What is a stream id?
    As you know, the pkts from Port A to Port B which in physical can consist of a stream, we call it 
    a stream, and it have an stream id, which maybe 0.

At <nl2fwd.h>
	<1> int dpdk_send_packet_dst(unsigned char *data, int datalen, int dst);
	    Send packets made by yourself to the tx port in stream <dst>
	<2> int dpdk_send_packet_port(const unsigned char *data, int datalen, int port);\
	    Send packets made by yourself to port <port>
	<3> int dpdk_init(int argc, char **argv);
	    Init the Intel DPDK envoriment.
	<4> int dpdk_run();
	    Start and run the worker and I/O thread created by Intel DPDK.
	<5> int dpdk_register_callfunc(int (*func)(const unsigned char *data,int datalen,int port_in,int lcore));
	    Register the function handle which provided by user, and the function will be called by packet process
	    function in worker thread.
	    * You can recieve the physical port number.
	<6> int dpdk_register_callfunc_dst(int (*func)(const unsigned char *data,int datalen,int dst,int lcore));
	    Register the function handle which provided by user, and the function will be called by packet process
	    function in worker thread.
	    * You can recieve the stream(destration) number.

	Note: You cannot use dpdk_register_callfunc() and dpdk_register_callfunc_dst together.


Complete and Install
==============================
	# make
	# make install
	
	It is so easy.

Rebuild DPDK
==============================
	If need to rebuild DPDK libs, type:
	# make dpdk
	It will use -fPIC and -g symbol to rebuild DPDK libs.

Link to your Application
==============================
    	$gcc -o test test.c -lnl2fwd
