Hi,
I am working on a new header format for radio packet meta information to
display in Wireshark.
I would like to request a new DLT value to use for this header. The format is
currently being defined, and is not yet final. I expect it to be within the
next few weeks.

OK, LINKTYPE_BLUETOOTH_LINUX_MONITOR and DLT_BLUETOOTH_LINUX_MONITOR have been
assigned the value 254.

It seems that new bluetooth DLT will be similar to existing LLCP:

Adapter Number -> Adapter Id (2 ocetets, network order)
Flags -> Opcode (2 octets, network order)
Payload -> Payload

You can see code in Wireshark side (great example, very similar, but
this is only support for capture file changes):

Hi Guy,
could you register a DLT for SCTP? It would be similar to
LINKTYPE_IPV4 / DLT_IPV4 or LINKTYPE_IPV6 / DLT_IPV6,
just covering the SCTP packet without any lower layer.
Suggested name: LINKTYPE_SCTP / DLT_SCTP.
Please let me know if you have any further questions.
Thanks a lot for your hel

No IPv4 or IPv6 headers, so no identification of the IP-layer endpoint
