is there a possibility to process the PPI-header on the fly while capturing pakets from multiple drones?
As the tap interface doesn't provide this header, there is only the possibility to get those data by processing the *.pcapdump file, right? I read, that there was the possibility in the past to get this header by a fifo named pipe but this feature was removed long ago.
My aim is to get somthing like this after processing:

[Sender-Mac];[CaptureDroneName e.g. Drone1];RSSI-Value1;RSSI-Value2;...;RSSI-ValueN;

The problem is that this processing should be an on going process without interruption like:
Kismet_start -> wait some time-> kismet stop -> processing -> delete old pcapfile-> kismet start -> wait some time -> kismet stop -> processing -> and so on ...

The problem with this basic approach is that the pcap file will grow unlimited as long as the kismet_server runs; but I don't need the package data anymore after processing...

I need this data for a RSSI based localisation system.
