If you think that choosing the type of protocol in reading application is not enough - well, let's call it DLT_IPMB_LINUX; we'll add the ability to select the DLT_ value in the capture utility.

Well, that would have the advantage that files are self-identifying. If the file is only ever read once, that's just a question of whether to indicate the file type when you do the capture or when you read the file; however, if it's read more than once, with a link-layer type that says "this is IPMB", you only have to specify when you capture.
