hostapd is not yet quite ready for this, but it is moving to that
direction and will hopefully be easier to use with other drivers in the
future. This is ongoing work, so any comments and/or patches on this
area are welcome.
wpa_supplicant was designed from the beginning to support multiple
drivers. It has already been used successfully with ten or so drivers. I
have used it with a driver that does not use Linux wireless extensions
at all, so that is not a problem either. I have tried to write enough
documentation for wpa_supplicant porting (developer.txt and documented
driver interface in driver.h). If this leaves something unclear, please
send more detailed question(s) and I'll add some more documentation.
