Subject: AX88179_178A USB3 ethernet adapter performance issue

Hi Freddy et al,

I'm experiencing poor network performance using an ASIX AX88179_178A
USB3 to ethernet adapter using any recent linux kernel (eg 3.11),
using an Intel XHCI USB3 controller.

Running iperf tests between one host with a gigabit PCIe NIC, via a
gigabit switch to the other host with various interfaces:

PCIe bcm957762: send 818Mb/s, recv 910Mb/s
USB2 smsc75xx: send 341Mb/s, recv 330Mb/s
USB3 ax88179_178a: send 347Mb/s, recv 18.7Mb/s

Are you able to reproduce the same 19Mb/s receive rate there?

Many thanks,
  Daniel
