本文从代码层面详细介绍了intel igb系列驱动程序的收发包流程。文档首先分析驱动程序中重要数结构及其结构中重要变量的作用,然后分析驱动的初始化流程,最后分析数据包从网卡队列中收取上来后驱动要做哪些操作并如何把数据包送入协议栈。及协议栈如何将数据包发送到驱动中,驱动如何将数据包放入网卡的发送队列。 文档中所...

At this point, the GbE interfaces have been reset and there were no saving/restoring of its PCIe state and there is no notification of this reset to the igb driver (if it was loaded and running). The GbE interfaces are no longer operational. Any network connections previously opened are ...
My problem is that the latest Intel igb driver does not build with more recent Linux kernels, e.g. the 6.1 branch. The issue has to do with a change in the NAPI driver model where the weight argument has been dropped. I attached the build logs to the previous post but here's the ...
Gigabit devices based on the Intel(R) Ethernet Controller X722 are supported by the i40e driver. igb-x.x.x.tar.gz Due to the continuous development of the Linux kernel, the drivers are updated more often than the bundled releases. The la...
