Skipping remaining errors on eth1...
Total: 20 on eth1
有没有出现过这样的问题，在netfpga.org上也查不到这样的信息。
我认为自己发现问题的根源了，但不知道该怎样解决，各位可不可以帮帮忙
谢谢了
具体问题是：当eth1接nf2c0、eth2接nf2c1时，下载完bit文件，打开各个nf2*后运行测试程序。
发现netfpga的每个网卡右边另外一个红灯（表示数据传输状态的吧）都不会亮的，而且网卡也没有反应。首先声明两块网卡都是好的，没有问题
但网卡和netfpga之间不能相互识别，这肯定是不可能发送和接收数据包的。
拿下eth1接nf2c0的网线，用我笔记本电脑上的网卡代替eth1时，笔记本和nf2c0的网口红灯都会亮，用wireshark可以看到相应的数据包。
不知道是否描述清楚问题了，大家做过的，或者正在做的帮帮忙，指导一下小弟，再次感谢～
