*
+ * @NL80211_CMD_REGISTER_ACTION: Register for receiving certain action frames
+ * (via @NL80211_CMD_ACTION) for processing in userspace. This command
+ * requires an interface index and a match attribute containing the first
+ * few bytes of the frame that should match, e.g. a single byte for only
+ * a category match or four bytes for vendor frames including the OUI.
+ * The registration cannot be dropped, but is removed automatically
+ * when the netlink socket is closed. Multiple registrations can be made.
+ * @NL80211_CMD_ACTION: Action frame TX request and RX notification. This
+ * command is used both as a request to transmit an Action frame and as an
+ * event indicating reception of an Action frame that was not processed in
+ * kernel code, but is for us (i.e., which may need to be processed in a
+ * user space application). %NL80211_ATTR_FRAME is used to specify the
+ * frame contents (including header). %NL80211_ATTR_WIPHY_FREQ (and
+ * optionally %NL80211_ATTR_WIPHY_CHANNEL_TYPE) is used to indicate on
+ * which channel the frame is to be transmitted or was received. This
+ * channel has to be the current channel (remain-on-channel or the
+ * operational channel). When called, this operation returns a cookie
+ * (%NL80211_ATTR_COOKIE) that will be included with the TX status event
+ * pertaining to the TX request.
+ * @NL80211_CMD_ACTION_TX_STATUS: Report TX status of an Action frame
+ * transmitted with %NL80211_CMD_ACTION. %NL80211_ATTR_COOKIE identifies
+ * the TX command and %NL80211_ATTR_FRAME includes the contents of the
+ * frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
+ * the frame.
