+ * @QCA_NL80211_VENDOR_SUBCMD_SET_MONITOR_MODE: This vendor subcommand is used
+ *     to set packet monitor mode that aims to send the specified set of TX and
+ *     RX frames on the current client interface to an active monitor interface.
+ *     If this Monitor mode is set, the driver will send the configured frames,
+ *     from the interface on which the command is issued, to an active monitor
+ *     interface. The attributes used with this command are defined in
+ *     enum qca_wlan_vendor_attr_set_monitor_mode.
+ *
+ *     Though the monitor mode is configured for the respective data/mgmt/ctrl
+ *     frames, it is up to the respective WLAN driver/firmware/hardware designs
+ *     to consider the possibility of sending these frames over the monitor
+ *     interface. For example, the control frames are handled with in the
+ *     hardware and thus passing such frames over the monitor interface is left
+ *     to the respective designs.
+ *
+ *     Also, this monitor mode is governed to behave accordingly in
+ *     suspend/resume states. If the firmware handles any of such frames
+ *     in suspend state without waking up the host and if the monitor mode
+ *     is configured to notify all such frames, then the firmware is expected
+ *     to resume the host and forward the respective frames to the monitor
+ *     interface. Please note that such a request to get the frames over the
+ *     monitor interface will have a definite power implications.
