I will not cover the API here but rather point you to the source code of a Python script that uses iperf3 and ethtool to detect network errors (as I did manually above). You can see it running below. Please check out therepositoryand run the script. You will be amazed at how easy...
ifconfig查看网卡的时候,可以里面有个overruns,表示因为环形队列满被丢弃的包。如果发现有丢包,可能需要通过ethtool命令来加大环形队列的长度。 网卡的硬中断注册的处理函数是igb_msix_ring。 //file: drivers/net/ethernet/intel/igb/igb_main.c static irqreturn_t igb_msix_ring(int irq, void *data) { struct...

我们在终端中输入sudo ethtool <设备名> | grep Wake-on可以看到网卡wol状态 sudo ethtool enp7s0 | grep Wake-on #我的网卡设备名是enp7s0 返回如下信息,其中Wake-on: b代表兼容性最差的BROADCAST模式 Supports Wake-on: pumbg Wake-on: b 但当我们用ethtool -s <设备名> wol g将wol设置为GENERIC后,...
其中,Bandwidth 可以用 ethtool 来查询,它的单位通常是 Gb/s 或者 Mb/s,不过注意这里小写字母 b ,表示比特而不是字节。我们通常提到的千兆网卡、万兆网卡等,单位也都是比特。如下你可以看到,我的 eth0 网卡就是一个千兆网卡: $ ethtool eth0 | grep Speed ...
