G'day,
Just a small update on the Unifi security gateway stuff. They have a new
range of devices which are a lot more powerful.

)
The good news is that the limits set in the GUI now match exactly the
"rate" set in the qcdisc.

So 35Mb/s and 800Mb/s match what is configured in the GUI.

The bad news is still no cake.
The bottleneck in my house is now the air interfaces. I'll run some flent
tests soon.
