I'd like to request a new DLT value for our internal header format.

We have a patched version of libpcap that can capture packets from our custom board. The board can optionally attach it's own header to the packets, before the Ethernet header. We
call it an RAIF1 header so something like DLT_RAIF1 would be good.

I can make more information available, but currently it's only really useful to our
customers that have a board.

I note that tcpdump, Snort, Wireshark, and ntop are mentioned on your company's website; will patches for any of those be distributed to handle DLT_RAIF1?

In addition, we might want to know what information is provided in the header, to guide future work on the pcap-NG file format and on tcpdump, Wireshark, etc..
