It appears everything is working in order. I have some issues with 160Hz wide channels but that is per client.
I'm topping 800mbps on iperf (80hz channel), I'd say pretty good!
All I'm missing now is SQM, can't install it since the snapshot is few days old.
Is there a way I could do it without creating an image from scratch?
Or, can @thorsten97 could share the build config?
