How to add support for new capture interface

Hi all! I have just written a trace port analyzer for ARMv7-M architecture microcontrollers. The trace datastream is sent over a serial port to the PC, where it is packed into frames and decoded. I'd like to present these data packets to the user using wireshark, as it already has a very nice and easy-to-use implementation of presenting packet data, and filtering them. On the wireshark list I was informed that it is using libpcap for capturing packet data, and in order to support my trace source I should extend libpcap. I would like to ask for your help to get started, how can I add a new interface to libpcap?. The hardware uses an FT2232 chip to capture the serial data and forward it to the PC over a USB connection. The FT2232 chip implements CDC, so it can be handled as a serial port as well. At this moment the libftdi and libusb user-space drivers are used to read data from the chip. Regards and thanks in advance, Ákos Vandra - This is the tcpdump-workers list.
