I just had another look at the D-Link DUB-E100: it has an Asix AX88172
chip, not AX88772. sorry for that. It worked right out-of-the box. it
is already mentioned in the 2.6.14 sources I have lying around here.

I didn't change anything concerning the DUB-E100 in the kernel sources,
so it uses the dlink_dub_e100_info struct and original USB_DEVICE
(0x2001, 0x1a00). Maybe you have a different revision (if there are
any), mine is 10.01 (taken from /proc/bus/usb/devices).
I haven't run ethtool on it. it's not on the system that's running a
stress test using the adapter.
My problem with the VIA-based systems and USB-to-ethernet adaptors
oopsing after a while is still not solved. I haven't seen it on
(large/fast) Intel/AMD-based systems, just on VIA-based systems (C3,
steppings 8 and 10), and only if such an adaptor is involved, not on
those with dual LAN on-board. It appears with Linksys USB200M,
D-Link DUB-E100, and a Digitus adaptor, all of which use the asix driver.
