My test script isn't performance, just features, and I'm thinking about
how/where to publish it...
You can also test UDP using -u w/ iperf3 and adjust the bandwidth w/
-b 300m (or other Mbps)...

Hmmm... The reverse seems slow, but I can't think of why it'd be that
slow though. When I did my tests on the USB2 ports, both directions
were about the same speed...
Thanks for the test! Great to hear things are working...
