@thomas955 - the i40 driver in 4.15 will not be updated. You may want to
try the 5.4 HWE kernel for 18.04 which I think should include the
patches to enable the x710-T2L. We only pulled the support back as

This appears to still be an issue on the latest 5.4.0-99-generic kernel.
I'm using a 2 port 10GSFP+ card. The PCI driver isn't bound according to
lspci, and the interfaces don't show up in dmesg or "ip

We also got new servers with the X710-T2L. The default i40e driver is
not working with the current kernel version:

For what it's worth, this doesn't just affect the X710-TM4 controller.
The X710-T2L card is rendered completely useless by this bug as that
card only has copper 10 GbE ports. As with the X710-TM4, the latest
version of the Intel driver fixes the issue.
Are there plans to release a fixed i40e
Per tester, the patched kernel does not resolve the issue.
At least we know the diff.
Also, did some bisecting with the Intel drivers upstream and this is the
earliest version where the card starts working again:
2.10.19.82
So it breaks sometime around 2.8.20 and then starts working again

The Intel x710-TM4 is one of the latest 10GbE controllers from intel
using the i40e driver. This particular 4 port comes in a 2x2
arrangement: 2x SFP+ and 2x RJ-45. This card is enabled in 5.4 via the

This seems to be the commit missing in 5.4. It landed in 5.5.

Asked them to start bisecting the driver versions from Intel to figure
out the earliest update that resolves the issue.
