I'm still not fully convinced this needs to be a fully separate
mechanism from netconsole. It seems a lot of work to implement
basically log level.
Maybe netconsole could be patched to support only dumping KERN_EMERG?
But I guess the structured logging has some advantages, although
there have been certainly oops parsers (e.g. kerneloops.org) without it.

fw_version and board_name is known by the kernel anyways through the DMI
interface, assuming the BIOS supplies that. We also dump it already
on a standard oops. So why not just use that directly?
As a general user ABI perhaps simply an unstructured string is better
that is included in the packet.
