thi is really strange, I'm running around 1000 debian vms in production,
wheezy with 3.16 kernel or jessie with 3.16, and I never had packets drop like this.

Just for the record, I tried with latest backport kernel, but we're
seeing the problem yet.
Today it has lost network 3 times (the last one with 3.16 bpo kernel),
this is a change since the previous about-1-week frequency...
