During AIO (All In One) installation, there is a step to update the kernel version of the OS. After the kernel version was updated, none of the "Ethernet 10G 2P X710 Adapter" network card devices came up after reboot.
During the Kernel update step of AIO installation, kernel version was downgraded from '3.16.0-30-generic ' to ' 3.13.0-171-generic '. This version is according to the contrail version '3.2.15.0-100~kilo'. After reboot, the following “Ethernet 10G 2P X710 Adapter“ network card devices did not come up:

In an attempt to get the interfaces up, a different driver version was installed for this adapter, like 'i40e-2.14.13 (latest driver version)', 'i40e1.3.38” and “i40e-1.3.39.1', but 'Intel Ethernet 10G 2P X710 Adapter' Interfaces were still down.
Procedure for the installation of a new driver version:
Note: Make sure you are on the old kernel version ' 3.16.0-30-generic' to have ssh connection to the system, as interfaces are not comping up on new kernel version.
Download the relevant driver tar file from the following link (According to the NIC) and move the tar file to your server at a location of your choice, such as /root/i40e:
Navigate to the location /root/i40e and 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
Change to the driver src directory, where <x.x.x> is the version number for the driver tar:
# cd i40e- <x.x.x> /src/
Compile the driver module:
Load the module using the modprobe command. To check the version of the driver and then load it:
modprobe
modinfo i40e modprobe i40e
Reboot the system to bring it back to the new kernel ' 3.13.0-171-generic' and check if the interfaces came up.
When checking the logs, the following errors were seen in dmesg:
