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:
Changelog for i40e 2.7.11 =========================================================================== Implement ADq feature Add support for configuring VFs through sysfs Add XDP support Add support Forward Error Correction (FEC) on 25G links Allow disabling FW LLDP (requires updated firmware) Fix bug where link could be forced down after MTU change Add support for new kernel APIs Fix WARN_ON() if MSI-X not available Fix issue with lost link when forcing link mode on some adapters Add support to allow the FW update tool to upgrade/downgrade from any FW version to any other FW version Note: this may require a power cycle as an intermediate step. Fix kernel panic with repeated quick enable/disable of VFs Fix possible TX timeout with DCB on some kernels Re-enable TSO after MTU change Fix potential panic on shutdown with many MSI-X vectors Add VEB stats to ethtool Fix panic on suspend with RDMA client driver active Fix timing issue with assigning VFs to VMs using virsh Restore TCPv4 input set when re-enabling ATR Performance fixes with Adaptive ITR Code cleanups Minor bug fixes Add support for RHEL 7.5 Add support for SLES12SP3 Source: README.txt, updated 2018-10-26

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
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
sudo apt install make gcc
Download the latest driver:
tar -xf i40e-2.7.11.tar.gz
Instructions are in the README — read them:
Install. This was performed while my X710-DA4 was not being used nor had assigned IPs:
rmmod i40e; modprobe i40e
Confirm updated driver:
ethtool -i enp1s0f0
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:
