I too am having the same problem, first I get a error "could't start - interface not up (6)" then when I press start again it shows me a little traffic on rx only just as the image above.
Edit: it only happens on queue's but when I torch the interface it works fine.
we are working to resolve problem that if you have queues enabled you do not see tx data in torch. Disabling queues helps, but that is not much of a workaround. So just hang on for the fix.
