Can we get a link layer header type assigned for this?

Yes, if we can get a specification for what the packets look like. :-)

There's the rub the format is internal :(

Where is the format of the packets that would appear with this link-layer header type documented?

It is mostly documented at http://training.clipsal.com/downloads/OpenCBus/Serial%20Interface%20User%20Guide.pdf

Although the format is slightly different (hence the internal stuff).

If that's not acceptable then I can keep using user DLTs easily enough - I wasn't sure what the rules were.
