Hello sit-valachil,

Welcome to the community!

Can you please tell us what server you are trying to install this on?

Lenovo Thinksystem ST550

1. Download Intel X722 latest driver 24.0-b on Lenovo web,

http://driverdl.lenovo.com.cn/lenovo/mig/2019/07/29/20536/intc-lnvgy_dd_nic_24.0-b_rhel7_x86-64.tgz 

2. Follow the attach readme to compile the drive in Ubuntu.

Building and Installation
-------------------------
To build a binary RPM* package of this driver, run 'rpmbuild -tb
i40e-<x.x.x>.tar.gz', where <x.x.x> is the version number for the driver tar
file.

Note: For the build to work properly, the currently running kernel MUST match
the version and configuration of the installed kernel sources. If you have just
recompiled the kernel reboot the system before building.

Note: RPM functionality has only been tested in Red Hat distributions.

1). Move the base driver tar file to the directory of your choice. For
   example, use '/home/username/i40e' or '/usr/local/src/i40e'.

2). Untar/unzip the archive, where <x.x.x> is the version number for the
   driver tar file:
   tar zxf i40e-<x.x.x>.tar.gz

3). Change to the driver src directory, where <x.x.x> is the version number
   for the driver tar:
   cd i40e-<x.x.x>/src/

4). Compile the driver module:
   # make install
   The binary will be installed as:
   /lib/modules/<KERNEL VERSION>/updates/drivers/net/ethernet/intel/i40e/i40e.ko

   The install location listed above is the default location. This may differ
   for various Linux distributions.

  NOTE: To gather and display additional statistics, use the
  I40E_ADD_PROBES pre-processor macro:
  #make CFLAGS_EXTRA=-DI40E_ADD_PROBES
  Please note that this additional statistics gathering can impact
  performance.

5). Load the module using the modprobe command:
   modprobe <i40e> [parameter=port1_value,port2_value]

   Make sure that any older i40e drivers are removed from the kernel before
   loading the new module:
   rmmod i40e; modprobe i40e (or use command: insmod i40e.ko, path: /lib/modules/<KERNEL VERSION>/updates/drivers/net/ethernet/intel/i40e/i40e.ko)

6). Assign an IP address to the interface by entering the following,
   where ethX is the interface name that was shown in dmesg after modprobe:
 
   ip address add <IP_address>/<netmask bits> dev ethX

7). Verify that the interface works. Enter the following, where IP_address
   is the IP address for another machine on the same subnet as the interface
   that is being tested:
   ping <IP_address>

Note: For certain distributions like (but not limited to) RedHat Enterprise
Linux 7 and Ubuntu, once the driver is installed the initrd/initramfs file may
need to be updated to prevent the OS loading old versions of the i40e driver.
The dracut utility may be used on RedHat distributions:
 # dracut --force
   For Ubuntu:
 # update-initramfs -u
