FYI we found these issues while deploying openstack via juju/maas over a pool of 8 nodes having 4x i40e NICs, where we also found linux-hwe-generic-trusty (lts-utopic) to be unreliable from its old i40e driver (0.4.10-k).
Below is a summary of our i40e findings using lts-vivid and lts-utopic re: successful completed deploys: #1 3.19.0-28-generic w/stock 1.2.2-k: non-phy mirrored frames (this bug) #2 3.16.0-49-generic w/stock 0.4.10-k: unreliable deploys #3 3.19.0-28-generic w/built 2.2.48: OK #4 3.16.0-49-generic w/built 2.2.48: OK -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-lts-vivid in Ubuntu. https://bugs.launchpad.net/bugs/1497812 Title: i40e bug: non physical MAC outbound frames appear as copied back inbound (mirrored) Status in linux-lts-vivid package in Ubuntu: New Bug description: Using 3.19.0-28-generic #30~14.04.1-Ubuntu with stock i40e driver version 2.2.2-k makes every 'non physical' MAC output frame appear as copied back at input, as if the switch was doing frame 'mirroring' (and/or hair-pinning). FYI same setup, with i40e upgraded to 1.2.48 from http://downloadmirror.intel.com/25282/eng/i40e-1.2.48.tar.gz behaves OK, fyi also we did a port mirroring setup at the switch directed to a different physical port for debugging, and didn't observe these frames to be physically present.
