Switch driver over from wext to cfg80211 interface. Some Notes: - This patch moves the driver wholesale from wext to cfg80211. Wext support is still provided through the cfg80211 provided wext compatability layer. - Currently only infrastructure mode is implemented. Ad hoc mode is not yet implemented, but can be added. - It does not support connecting to a specified bssid, instead roaming is handled by the card itself. This matches the behaviour of the existing driver. - It has been tested using NetworkManager (via wpa_supplicant) configured to use the wext compatability layer, and then again with the native nl80211 layer.
