+ * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
+ *      (or GO) interface (i.e. hostapd) to ask for unexpected frames to
+ *      implement sending deauth to stations that send unexpected class 3
+ *      frames. Also used as the event sent by the kernel when such a frame
+ *      is received.
+ *      For the event, the %NL80211_ATTR_MAC attribute carries the TA and
+ *      other attributes like the interface index are present.
+ *      If used as the command it must have an interface index and you can
+ *      only unsubscribe from the event by closing the socket. Subscription

+ *
+ * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the

+ * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
+ *      by sending a null data frame to it and reporting when the frame is
+ *      acknowleged. This is used to allow timing out inactive clients. Uses
+ *      %NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a

+ * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
+ *      other BSSes when any interfaces are in AP mode. This helps implement
