Linux 有问必答: 如何在红帽系linux中编译Ixgbe驱动

提问：我想要安装最新版的ixgbe 10G网卡驱动。在CentOS, Fedora 或 RHEL中，我应该如何编译ixgbe驱动？

想要在linux使用Intel的PCI Express 10G网卡（例如，82598，82599，x540），需要安装Ixgbe驱动。如今的Linux发行版都会预安装ixgbe的可加载模块，但是预安装的ixgbe驱动不是完整功能版。如果想要开启和定制所有10G网卡的功能（如，RSS、多队列、虚拟化功能、硬件 offload 等），需要从源码编译安装。

本文基于红帽系平台（如，CentOS，RHEL或Fedora）。Debian系平台，请看这篇文章

第一步: 安装依赖

首先，安装必要的开发环境和安装匹配的内核头文件

$ sudo yum install gcc make
$ sudo yum install kernel-devel

第二步: 编译Ixgbe

从官方页面下载最新Ixgbe源码

$ wget http://downloads.sourceforge.net/project/e1000/ixgbe%20stable/3.23.2/ixgbe-3.23.2.tar.gz

请检查支持的内核版本。例如，Ixgbe3.23.2版本支持Linux内核版本2.6.18到3.18.1。

提取压缩包并编译

$ tar -xvf ixgbe-3.23.2.tar.gz
$ cd ixgbe-3.23.2/src
$ make

如果成功，可以在当前目录找到编译完成的驱动（ixgbe.ko）。

可以运行这个命令来查看编译信息：

$ modinfo ./ixgbe.ko

将会输出一个Ixgbe驱动的可用参数列表

第三步: 加载 Ixgbe 驱动

这步准备加载已经编译好的驱动。

如果系统已经加载了Ixgbe驱动，首先需要卸载掉老版本。否则，新版本不能加载。

$ sudo rmmod ixgbe.ko

然后插入编译完成的驱动到内核中：

$ sudo insmod ./ixgbe.ko

同时，你可以设置启动参数

$ sudo insmod ./ixgbe.ko FdirPballoc=3 RSS=16

验证驱动是否加载成功，使用dmesg命令，查看其输出

$ dmesg

第四步: 安装Ixgbe驱动

当确认驱动已经加载后，就可以安装驱动到系统中了

$ sudo make install

ixgbe.ko将会安装在下列目录

/lib/modules/<kernel-version>/kernel/drivers/net/ixgbe

此时，编译好的驱动将在启动时自动加载，也可以通过运行命令加载它：

$ sudo modprobe ixgbe
