最近碰到问题，linux系统中总是丢包，统计如下：

rx_missed_errors: 10005  rx_no_buffer_count: 0  应该不是缓冲区不够引起的丢包。不知道在linux中还有那些原因导致丢包了呢？

最近也在研究大流量冲击下，内核网络的处理。
我发了一个帖子，可以共同研究一下：
http://bbs.csdn.net/topics/390634978

目前就我了解的来看，我认为大流量下丢包和物理内存大小以及中断频繁关系比较大。
上半部往下半部的队列中放，如果这个队列达到了max，就丢包。
还有可能是真的没有物理内存了，连分配skb空间的内存也没有了应该也丢包吧？

网卡貌似自己也有外存，这个满了应该也可能。

有帖子说过用ethtool改变网卡的buffer，你可以看看这么改效果好不。我还没试过，我设备裁剪过，用不了ethtool。

物理内存不够很好确认的，一般不会。大流量冲击是会导致丢包，但是楼主是不是大流量还不知道呢。

收报时全部集中在几个rx_quene?
