Hi Marc,
I've taken a look at the driver you linked to and compared it to the
version that was closest at the time.
This is similar to the patch they must have had at some point. I would guess
that the answer is somewhere in there. It's quite different to the much
cleaner patch 933a27d39e "USB: asix - Add AX88178 support and many other
changes", which was merged later with a similar intention.
