axge info

Hello,
I'm experiencing performance issues with a USB 3.0 adapter using ASIX 88179
chipset [1], that should be supported by "axge" driver [2]

Basically, speed is not above ~530Mb/s, even though the device is correctly
recognized as Usb 3.0 if running an iperf3 client test, while it's ~180Mb if
running a iperf3 server on the machine and trying to connect from a Linux
client.

If trying to use Debian 9 on the same machine, I'm not experiencing any issue,
like described in this forum thread [3]. 

You can find more details attached to this post.

Please let me know if there's any further info I should provide.

Thank you.
Regards,
Alessandro
