-Subject: hostapd: Add an option to notify management frames on ctrl_iface
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-In some contexts (e.g., Multi-AP) it can be useful to have access to
-some of the management frames in upper layers (e.g., to be able to
-process the content of association requests externally).
-
-Add 'notify_mgmt_frames'. When enabled, it will notify the ctrl_iface
-when a management frame arrives using the AP-MGMT-FRAME-RECEIVED event
-message.
-
-Note that to avoid completely flooding the ctrl_iface, not all
-management frames are included (e.g., Beacon and Probe Request frames
-are excluded).
