What's the need for a new driver interface? Doesn't the driver support
latest WEXT? If not, could that be added instead of modifying

That would sound fine.

What would you be changing in these? I would not have expected
driver-specific changes to be needed in these files..

If you really need a new driver interface (i.e., driver_wext.c or
driver_nl80211.c won't do it for some good reason), I can include it in
the wpa_supplicant distribution, but it would be fine to keep it as an
OpenWRT patch, too.
