Belkin F5D5055 not really working with the asix driver

Hi, I got a belkin f5d5055 usb 2.0 gigabit adapter that should be
supported by usbnet + the asix driver, still although recognized it
doesn't actually work. More specifically, the card is recognized, the
interface is created and brought up etc only no packets flow from/to
the device.

I tried the exact same card, cable and router combination with windows
and it works fine (ping, dhcp everything) so I suspect the driver
might be the problem.

I recompiled with debug information enabled and I attach the trace,
hoping it will help.
I can also provide usbmon traces and a usbsnoop trace from the windows
machine where it works if needed.

Unfortunately I don't have the time to dig through the datasheets/code
to fix the problem myself :(

Thanks in advance.
