Public bug reported:

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.

See tcpdump -P in/out and more details at
