Posted to linux-usb list with cc to Freddy Xin (who introduced the
driver to the list).

Title:
  0b95:1790 [Asus N55SF] Bad performance of Asix Ethernet-to-USB device
  on USB3 port

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  Plugging USB-to-ethernet device ID 0b95:1790 ASIX Electronics Corp. in
  USB3 port yields slow performance, dmesg flooded with errors. Plugging
  on USB2 port, exact same situation otherwise, works well. This is
  reproducible 3 out of 4 attempts. Machine has 2 USB3 ports on the
  left, 2 USB2 ports on the right.

  ### When working (USB2 port)
  * ethernet auto-negociation is fast
  * mii-tool is fast (typical 0.05s)
  * few lines in dmesg
  * good performance

  ### When failing :
  * ethernet auto-negociation fails, then sometimes eventually works
  * mii-tool is slow (10s of seconds instead of 0.05s)

  time sudo mii-tool
  eth0: no link
  eth1: 10 Mbit, half duplex, no link
  real	0m40.014s
  user	0m0.013s
  sys	0m0.006s

  time sudo mii-tool
  eth0: no link
  eth1: 10 Mbit, half duplex, no link
  real	0m50.015s
  user	0m0.011s
  sys	0m0.011s

  time sudo mii-tool
  eth0: no link
  eth1: negotiated 100baseTx-FD, link ok
  real	0m10.051s
  user	0m0.000s
  sys	0m0.012s

  But on some attempts mii-tool is fast...
  time sudo mii-tool
  eth0: no link
  eth1: negotiated 100baseTx-FD, link ok
  real	0m0.057s
  user	0m0.011s
  sys	0m0.012s

  * DHCP eventually completes (after about 30 seconds) then ethernet works.
  * whole system behaviour feels a little sluggish (not very clear, though)
  * mii-tool still slow (10s of seconds instead of 0.05s)

  ## dmesg when failing

  Full dmesg attached.

  Specific lines with occurrence count at random point (obtained with
  "dmesg | sed 's/^................//' | sort | uniq -c | sort -n" ).
