For the record, I won't block patches adding this kist to virtio
on the basis that they must be generic. It's not a lot
of code, implementation can come first, prettify later.

But we do need to have a discussion about how devices are paired.
I am not sure using just MAC works. E.g. some passthrough
devices don't give host ability to set the MAC.
Are these worth worrying about?
