>From what I understand host can tell firmware in what IE tags it is
interested in. When a beacon with a different IE tag (in which host
expressed interest in) content is seen it'll be sent up to the host,
otherwise it won't. For your purpose I suppose you want an empty
ie_map (i.e. full of zeros?).

Btw. The command should be actually:

struct wmi_add_bcn_filter_cmd {
 __le32 vdev_id;
} __packed;
