Comment 2 for bug 1497812

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
