Hey Viktor, I like your idea of focusing on simplicity, helps keeps the issue we are talking about clear. :)
To further this trend, can you verify your traffic generator is just producing SYN egress packets? If so have you seen the same issue using more "normal" traffic (i.e. several instants of netperf running in parallel)? If my assumption (your generator is only producing SYN egress packets) above is correct this is an interesting issue. Since the driver doesn't have anything to do with our egress queue selection, netdev sends us what it will on whatever queue it chooses. However you seem to be able to effect this choice by turning off ATR while using Vlan's? This is why I would like to know if you see this behavior without using the traffic generator.
