Howdy netdev folks,

Here are the details. If somehow their driver could be integrated in
mainline by putting the relevant bits in the current driver, that would be
fantastic :)
(obviously it would have been better if they had done that themselves to
start with, no idea why they didn't).

----------------------------------------------------------------------------

I just bought a USB gige ethernet adapter from 'winstars' called 'delphi g
usb 2.0 gigabit lan'.

Linux 2.6.39.1 says:
usb 8-1: Product: AX88178 
usb 8-1: Manufacturer: ASIX Elec. Corp.
usb 8-1: SerialNumber: 000002
asix 8-1:1.0: eth1: register 'asix' at usb-0000:00:1d.7-1, ASIX AX88178 USB 2.0 Ethernet, 00:0e:c6:88:7c:ae
usbcore: registered new interface driver asix

but that driver brings up an eth1 that cannot send data.

Google showed me the vendor website with a working linux driver:
http://www.asix.com.tw/FrootAttach/driver/AX88772_772A_178_LINUX2.6.9_REV122.zip

Their driver which compiled out of tree easily and said:
ASIX USB Ethernet Adapter:v4.1.0 19:16:59 Jun 28 2011
<6>    http://www.asix.com.tw
eth%d: status ep1in, 8 bytes period 11
eth1: register 'asix' at usb-0000:00:1d.7-1, ASIX AX88178 USB 2.0 Ethernet, 00:0e:c6:88:7c:ae
usbcore: registered new interface driver asix
eth1: rxqlen 0 --> 5
eth1: ax88178 - Link status is: 0
eth1: kevent 4 scheduled
eth1: ax88178 - Link status is: 1
eth1: no IPv6 routers present

It worked fine with dhcp (which the stock driver sure didn't).

Is there someone who can see if that driver can be merged in mainline to
replace the non working one?

For comparison, the mainline one also outputted a traceback. The full relevant logs are below:

(tcpdump showed some traffic though)

Later, I found this in dmesg:
