OK, sure thing. Is this on ASPEED hardware?

Yes, I think this matches our designs too; I don't see us needing
bridging at present.

Oh, interesting, I didn't expect folks to be using MCTP but not
including the host channel. There's no issue with that, so I'll update
the wording so it's clear that this can be accommodated.
