Wireless Sniffer Streaming, missing the RadioTap part

RouterOS Wireless Networking

I’m doing some test with an RB952Ui-5ac2nD.with ros 6.34.4
I’m trying to using the stream from wireless sniffer.
I noticed that there is no way to filter the packet before send them to the streaming. Am I wrong?
I also noticed that the radiotap part is missing in the streamed data (for example the signal strenght). There is a way to have these data streamed? The packets sent to stream have type 105 and not 127.
Thanks

I also note that there is no frame check sequence, nor do 802.11 ACKs show in the stream. Are there any other limitations?

I suspect the radiotap header is never put on the frame prior to sending, though a TZSP header is present:

TZSP: IEEE 802.11: Good
    Version: 1
    Type: Received packet (0)
    Encapsulates: IEEE 802.11 (18)
    Signal
        Option Tag: Signal (10)
        Option Length: 1
        Signal: -88
    Rate
        Option Tag: Rate (12)
        Option Length: 1
        Rate: 11 Mbit/s (22)
    Frame check sequence
    Channel
    Original Length
    End

The FCS value is indicated as ‘Good’, but there is no numeric value. Are bad frames passed as well? Many dataframes show with rate as Unknown (0), so are these at 802.11n rates? Any way to know the capabilities of what will be sent, or do we have to reverse engineer?


This is all I found in the Wiki documentation:

Packets

Sub-menu: /interface wireless sniffer packet

Sub-menu shows captured packets.

There is some info here http://wiki.mikrotik.com/wiki/Manual:Tools/Packet_Sniffer, but not much regarding wireless captures.
