Mulitcase:
Test with SmartBit
1. WAN port send traffic flow (multicast-stream, 1000bytes, 100% rate) to LAN port.
2. WAN to LAN throughput is 95%

测试步骤：

使用VLC 0.7.2进行测试
1.板子wan端连在hub上，hub上同时连一台pc，ip地址设置为固定IP；
2.板子lan端连另一台pc,自动获取ip(192.168.254.100);
3.lan端pc运行VLC-0.7.2:(client)
file->Open Network Stream->UDP/RTP Multicast->Address:224.1.2.3 Port:1234->OK
4.wan端PC运行VLC-0.7.2:(server)
a. Settings->Preferences->Stream output->勾选Advanced options->
勾选Keep stream output open->Time to live:2->Save->Ok
b. file->Open File->Browse(选择一个avi格式视频文件)->勾选Stream output->
Settings->UDP->Address:224.1.2.3 Port:1234->OK
c. OK
5.从lan端pc的VLC界面上可以看见server端放的视频文件。
注：使用码率比较高的视频文件，或者同时播多个文件测试
