Updated.  We shouldn't be adding new drivers to wpa_supplicant, but
fixing the kernel drivers to correctly implement WEXT.

mac80211 doesn't work well enough with WEXT yet, but work is ongoing in
that area.  mac80211 is still an experimental stack and in no way
'stable'.  You may experience problems while using it with tools other
than 'iwconfig', or even with 'iwconfig'.

Thx for this tips Dan i will work this way with hostapd next week...
but now how WE-22 can be implemented if wireless-tools isn't rebuilt for fc7?
https://bugzilla.redhat.com/234725 ?

I suppose the same problem will occurs as Fedora Core 5 had when WE
were updated inside the kernel. it was so difficult to update
Wireless-tools because it was required by
most of the packages involved in wireless (NetworkManager and so many others...)

Why wireless-tools cannot be build against new kernel (and WE-22 ?)
