Linux FAQs with Answers--How to compile ixgbe driver on CentOS, RHEL or Fedora
================================================================================
> **Question**: I want to build and install the latest ixgbe 10G NIC driver. How can I compile ixgbe driver on CentOS, Fedora or RHEL?
To use Intel's PCI Express 10G NICs (e.g., 82598, 82599, x540) on your Linux system, you need to install ixgbe driver. While modern Linux distributions come with ixgbe driver pre-installed as a loadable module, the pre-built ixgbe driver is not fully customizable with limited parameters. If you want to enable and customize all available features of the 10G NICs (e.g., RSS, multi-queue, virtual functions, hardware offload), you will need to build the driver from the source.
Here is how to compile ixgbe driver from the source on Red Hat based platforms (e.g., CentOS, RHEL or Fedora). For Debian based systems, refer to [this guideline][1] instead.
### Step One: Install Prerequisites ###
First, set up necessary developmen environment and install matching kernel headers.
$ sudo yum install gcc make
$ sudo yum install kernel-devel
### Step Two: Compile Ixgbe Driver ###
Download the latest ixgbe source code from the [official site][2].
$ wget http://downloads.sourceforge.net/project/e1000/ixgbe%20stable/3.23.2/ixgbe-3.23.2.tar.gz
Be sure to check supported kernel versions. For example, the ixgbe driver 3.23.2 supports Linux kernel versions 2.6.18 up to 3.18.1.
Extract the tarball and compile it.
$ tar -xvf ixgbe-3.23.2.tar.gz
$ cd ixgbe-3.23.2/src
$ make
If successful, the compiled driver (ixgbe.ko) will be found in the current directory.
You can check the information of the compiled driver by running:
$ modinfo ./ixgbe.ko
The output will show a list of available parameters of the ixgbe driver.

### Step Three: Load Ixgbe Driver ###
Now you are ready to load the compiled ixgbe driver.
If the stock ixgbe driver is already loaded on your system, you need to unload it first. Otherwise, you won't be able to load the new ixgbe driver.
$ sudo rmmod ixgbe.ko
Then insert the compiled driver in the kernel by running:
$ sudo insmod ./ixgbe.ko
Optionally, you can supply any parameters while loading the driver.
$ sudo insmod ./ixgbe.ko FdirPballoc=3 RSS=16
To verify that the driver is loaded successfully, check the output of dmesg command.
$ dmesg

### Step Four: Install Ixgbe Driver ###
Once you have checked that the driver is loaded successfully, go ahead and install the driver on your system.
$ sudo make install
ixgbe.ko will be installed in the following location.
/lib/modules/<kernel-version>/kernel/drivers/net/ixgbe
At this point, the compiled driver will be loaded automatically upon boot, or you can load it by running:
$ sudo modprobe ixgbe
