Updating Intel’s i40e driver in Ubuntu 18.10

No, Canonical does not provide the latest stable Intel i40e driver in the latest version of Ubuntu Server. In fact it’s 12 months old.

No, Intel does not keep the most current version of the i40e driver on Intel.com. It’s on SourceForge.

Let’s look at all of the REALLY IMPORTANT changes made to the i40e driver since version 2.3.2 that’s installed by default in Ubuntu 18.10:

I have already updated the X710-DA4 firmware (to 6.01) prior to updating the driver, but I have not read anywhere that updating the firmware first is necessary.

I started by looking at my installed drivers, but this is not needed, and does not show the versions of the driver:

ls -R /lib/modules/`uname -r`/kernel/ > drivers.log

Show current i40e driver:

ethtool -i enp1s0f0

Output:

driver: i40e
version: 2.3.2-k
firmware-version: 6.01 0x800035ce 1.1747.0
expansion-rom-version:
bus-info: 0000:01:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes

Install dependencies:

sudo apt install make gcc

Download the latest driver:

wget https://cfhcable.dl.sourceforge.net/project/e1000/i40e%20stable/2.7.11/i40e-2.7.11.tar.gz

Unzip:

tar -xf i40e-2.7.11.tar.gz

Instructions are in the README — read them:

vim i40e-2.7.11/README

Install. This was performed while my X710-DA4 was not being used nor had assigned IPs:

sudo su
cd i40e-2.7.11/src/
make install
rmmod i40e; modprobe i40e
update-initramfs -u
exit

Confirm updated driver:

ethtool -i enp1s0f0

Output:

driver: i40e
version: 2.7.11
firmware-version: 6.01 0x800035ce 1.1747.0
expansion-rom-version:
bus-info: 0000:01:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes

Don’t forget to read the included README for performance tuning options, and the over 2 year old Intel Ethernet Controller X710/XL710 and Intel Ethernet Converged Network Adapter X710/XL710 Family Linux Performance Tuning Guide from March 2016:

https://www.intel.com/content/dam/www/public/us/en/documents/reference-guides/xl710-x710-performance-tuning-linux-guide.pdf

Oh and:

sudo vim /etc/default/grub

Like this:

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=2
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on iommu=pt pcie_aspm=off"
GRUB_CMDLINE_LINUX="intel_iommu=on iommu=pt pcie_aspm=off"
sudo update-grub
sudo shutdown -r now
