Pawel may have more detail, but to me the significant difference
is that virtio-mmio is an implementation of a specification extension
agreed with the virtio spec maintainers, whereas syborg doesn't seem
to be mentioned in the virtio spec anywhere, so I am unsure what it
is intended to be implementing.
(There are some technical differences too, like virtio-mmio allowing
the guest to specify queue sizes and alignments; these mostly came
out of the process of agreeing the spec extension.)
