The patch [0] is present in Ubuntu releases starting with Focal, so it should be fixed for that and later releases (including current bionic- hwe). I'll look into backporting and testing this for Xenial and Bionic GA.

Matching subscriptions: Ubuntu 16.04 Bugs https://bugs.launchpad.net/bugs/1772675 Title: Intel i40e PF reset due to incorrect MDD detection (continues...again...) Status in linux package in Ubuntu: Fix Released Status in linux source package in Xenial: In Progress Status in linux source package in Bionic: In Progress Status in linux source package in Cosmic: Won't Fix Bug description: [impact] The i40e driver sometimes causes a "malicious device" event that the firmware detects, which causes the firmware to reset the nic, causing an interruption in the network connection - which can cause further problems, e.g. if the interface is in a bond; the reset will at least cause a temporary interruption in network traffic. [fix] The fix for this is currently unknown. As the "MDD event" is generated by the i40e firmware, and is completely undocumented, there is no way to tell what the i40e driver did to cause the MDD event. [test case] the bug is unfortunately very difficult to reproduce, but as shown in this (and previous) bug comments, some users of the i40e have traffic that can consistently reproduce the problem (although usually on the order of days, or longer, to reproduce). Reproducing is easily detected, as the nw traffic will be interrupted and the system logs will contain a message like: i40e 0000:02:00.1: TX driver issue detected, PF reset issued [regression potential] unknown since the specific fix is unknown. [original description] This is a continuation from bug 1713553 and then bug 1723127; a patch was added in the first bug and then the second bug, to attempt to fix this, and it may have helped reduce the issue but appears not to have fixed it, based on more reports. See bug 1713553 and bug 1723127 for more details.
