Well, first of all, Linux Wireless Extensions v18 has not been released
and is subject to change. In addition, the current proposal for v18 does
not probably include all the functionality needed for access point mode,
but many parts of it could be used to get partial functionality with
whatever remains to be filled either as private extensions or an updated
proposal for WE v18.

Well, I would say specific to a driver interface, not to a driver, i.e.,
more than one driver can share the same interface for interaction with

There is no v18 WE API implementation in hostapd, so no, that would not
make it easier for you. However, implementing a new driver_wext.c
interface (in the same way as in wpa_supplicant) would help people doing
the same thing in the future.
