It simply does not compute for me. You're exposing a very advanced vDPA
interface, and yet you say you don't need any network configuration
beyond what Niantic had.

There are no upstream-minded users of IPUs, if it was up to me I'd flat
out ban them from the kernel.

Seems reasonable, if it doesn't live in networking and doesn't use any
networking APIs it won't matter to me.
