The first thing I would like to see is an addition to Linux wireless
extensions for WPA/WPA2 so that we can get rid of the private ioctls in
the drivers. Even though these can often be similar, it would be nice to
just write one driver interface code in wpa_supplicant and have it
working with all Linu drivers.. I hope to find some time to write a
proposal for this.
One of the things that is nice about wireless-2.6 is that is affords the
opportunity to totally rethink the wireless extensions.
Although a lot of people would howl, since HostAP is essentially new
code from the mainline kernel perspective, a new userland API (and new
or updated tools) could come along with it.
I have mentioned in the past (no offense Jean!) that I do not like the
overly-generic wireless handler structure. It is less type-safe than is
generally preferred in Linux, IMO.
A low-level wireless driver should not implement ioctls, it should
implement callbacks in some sort of 'struct wireless_operations' as is
done in other kernel subsystems.
ioctl details should be hidden from low-level drivers as much as
possible, through type-safe interfaces. Strive to make both the
wireless driver API and the wireless userland API easy to change and
evolve over time.
