I thought we wanted to keep single message for one kind of functionality, which
is mmap related quirks here. And so it would be better if we can
mapping requirements.
When this feature is negotiated, the front-end can send the
'VHOST_USER_CUSTOM_MMAP' message type to provide the additional
information to the back-end.

Hello,
In my earlier attempt [1], I implemented the vhost-user-i2c backend
deamon for QEMU (though the code was generic enough to be used with
any hypervisor).
And here is a Rust implementation of the vhost-user-i2c backend
daemon. Again this is generic enough to be used with any hypervisor
