怎么写linux网卡驱动程序

方法一：

1：ethtool -i ethx

如：

linux:/mnt # ethtool -i eth1

driver: e1000e

version: 1.0.2-k2

firmware-version: 1.9-0

bus-info: 0000:0b:00.0

linux:/mnt # ethtool -i eth16

driver: igb

version: 2.1.0-k2

firmware-version: 1.4-1

bus-info: 0000:0a:00.0

linux:/mnt #

2：使用 modinfo igb 查看驱动信息

linux:~ # modinfo igb

2：使用 modinfo igb 查看驱动信息

(结果同方法一中的)

vmware虚拟机安装网卡驱动的具体步骤如下：

需要准备的材料分别是：电脑、vmware。

1、在开始菜单，双击打开VMware软件。

2、在VMware主界面的菜单栏中，单击编辑选项卡。

3、在d出下拉菜单中，选择虚拟网络编辑器。

4、在“虚拟网络编辑器”界面上，点击“添加网络”按钮。

5、单击提示中的确定选项。

6、此时就能看到虚拟网络编辑器中多了一个虚拟网卡，至此，安装过程完成。
