While I agree with the part that drivers should really use WEXT, my
policy on driver specific interface implementations for wpa_supplicant
is quite a bit more open than the one for NM. However..

This is an issue. I will not apply any random patch from a vendor that
someone else sends to me, especially so, if there is no clear license
statement or the change is licensed only under GPL. In other words, if
someone really wants to get this patch into wpa_supplicant, that someone
will need to talk with the copyright holder and confirm that this patch
is available under a compatible (both GPLv2 and BSD) license. In many
cases, it may be easier to just get the driver converted to support
WE-18 for WPA configuration..
