+ Disassociation frames when the STA is in power save sleep. Only
+ available with drivers that provide TX status events for Deauth/
+ Disassoc frames (nl80211).

+ at build time.
+ * atheros: Add support for IEEE 802.11w configuration.

+ config parameter ieee80211n.
+ * Allow AP mode to disconnect STAs based on low ACK condition (when
+ the data connection is not working properly, e.g., due to the STA
+ going outside the range of the AP). Disabled by default, enable by
+ config option disassoc_low_ack.
+ * nl80211:
+ - Support GTK rekey offload.
+ - Support PMKSA candidate events. This adds support for RSN
+ pre-authentication with nl80211 interface and drivers that handle

+ - Add DBus property CurrentAuthMode.
+ - P2P DBus API added.

+ network in scan results) using scan_interval command.
+ - Add event CTRL-EVENT-ASSOC-REJECT for association rejected.
+ - Add command get version, that returns wpa_supplicant version string.
+ - Add command sta_autoconnect for disabling automatic reconnection
+ on receiving disconnection event.

+ used to clear the bssid_set flag in a network block, i.e., to remove
+ bssid filtering.
+ - Add tdls_testing command to add a special testing feature for
+ changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be
+ enabled as well.

+ be compatible with Windows 7.
+ - Add Config Error into WPS-FAIL events to provide more info to the
+ user on how to resolve the issue.
+ - Label and Display config methods are not allowed to be enabled
+ at the same time, since it is unclear which PIN to use if both
+ methods are advertised.
+ - When controlling multiple interfaces:
+ - apply WPS commands to all interfaces configured to use WPS
+ - apply WPS config changes to all interfaces that use WPS
+ - when an attack is detected on any interface, disable AP PIN on
+ all interfaces

+ explicitly not supported, disable all user facing TDLS operations.
+ - Allow TDLS to be disabled at runtime (mostly for testing).
+ Use set tdls_disabled.
+ - Honor AP TDLS settings that prohibit/allow TDLS.
+ - Add a special testing feature for changing TDLS behavior. Use
+ CONFIG_TDLS_TESTING build param to enable. Configure at runtime
+ with tdls_testing cli command.
+ - Add support for TDLS 802.11z.
+ * wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
+ wlantest can be used to capture frames from a monitor interface
+ for realtime capturing or from pcap files for offline analysis.
+ * Interworking: Support added for 802.11u. Enable in .config with
+ CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters
+ for interworking. wpa_cli commands added to support this are

+ and stop_fetch_anqp.
+ * Android: Add build and runtime support for Android wpa_supplicant.
