fix wired IEEE 802.1X authentication
* fixed IEEE 802.11r key derivation function to match with the standard
(note: this breaks interoperability with previous version) [Bug 303]
+ * added better support for drivers that allow separate authentication
+ and association commands (e.g., mac80211-based Linux drivers with
+ nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol
+ to be used (IEEE 802.11r)
2009-01-06 - v0.6.7
* added support for Wi-Fi Protected Setup (WPS)
