I got a sample driver from ASIX for the AX88179A chipset and they allow me
to use it to write a driver but they won't allow me to publish it :(
ASIX recomended to use the CDC/NCM interface of the chipset, but OpenBSD
has no driver for CDC/NCM. Looking at the USB descriptor it turns out,
that it also has a configuration for CDC/ECM.
If you try the patch below, the AX88179A should attach via cdce(4). Don't
know if this is the way to go, but at least you should be able to use
your adapters.
Good luck,
Gerhard
