This article mainly explains "how to upgrade the network card driver under Linux". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how to upgrade the network card driver under Linux".

Update the network card driver under linux. Check the network card version

Ifconfig-a check the name of the network card

Suppose the network card found out is named eno1.

Ethtool-I eno1 / / View the current Nic driver version

It is known that the network card eno1 depends on the igb driver.

Version 5.3.5.20 (updated)

Lspci | grep net / / View the Nic model

The network card model is Intel I210.

Then go to the Intel official website to download the corresponding driver.

Https://downloadcenter.intel.com/zh-cn/download/13663/-82575-82580-i350-i2101-linux-

After downloading, upload it to the server

Before installation, make sure that the system kernel-headers, kernel-firmware, kernel-devel software packages have been installed, and the version must be the same, and the compilation tools gcc, gcc-c++ have been installed, if not installed, please configure the correct yum source and use the yum command to install.

Rpm-qa | grep ^ kernel / / View the installed kernerl

Rpm-qa | grep ^ gcc / / View the installed gcc compilation tool

View the kernel version of the server

Uname-r

Cd / usr/src/kernels/ looks for the corresponding kernel source code in the directory

Cd.. Go back to the upper directory, which is cd / usr/src/

Then perform a soft connection to the corresponding kernel source

Ln-s kernels/4.4.128-12.rcserver.x86_64/ linux

Go to the directory in the upload package and decompress the uploaded files

Tar zxf igb-5.3.5.22.tar.gz

Go to the cd igb-5.3.5.22/src/ directory

Then execute make install to compile.

After compiling, we will find that there will be an igb.ko file in the current directory, which is the Nic driver we compiled.

Then replace the igb.ko to the following directory. It is possible that the catalog is different. You can use modinfo igb to view the path of the current driver, and then replace it as appropriate.

/ lib/modules/4.4.128-12.rcserver.x86_64/kernel/drivers/net/ethernet/intel/igb/igb.ko

Then unload the driver and load the new driver. (note uninstalling the old driver will disconnect the network, so you can put the new driver on the root directory in order to perform the operation)

Rmmod igb / / Uninstall

Insmod igb.ko// loading (needs to be executed under the current directory of early igb.ko)

Depmod-a / / analyze all available modules

Ethtool-I eno1 will find that the driver version has changed.

Finally restart or service network restart restart the network service

Depmod-a / / analyze all available modules

Cp / boot/initramfs-4.4.128-12.rcserver.x86_64.img / boot/initramfs-4.4.128-12.rcserver.x86_64.img.bk / / make a copy before operation

Mkinitrd-f / boot/initramfs-4.4.128-12.rcserver.x86_64.img 4.4.128-12.rcserver.x86_64 / / mkinitrd can create an image file for Linux to load ramdisk when booting

Note: initramfs-4.4.128-12.rcserver.x86_64.img makes input according to its own actual situation.
