Hi Michael,

Currently, only VFs are supported. In subsequent patches we will have
devlink support to control which VF is used for VDPA and which function
is used for regular networking.

This confuses people and some drivers (notably vdpa)

It only supports modern guests so we could punt and
just force LE, but let's use the full virtio APIs since people
tend to copy/paste

We detect that config space is accessed before features are
set and set features to 0 automatically.
Note: some legacy guests might not even access config space, if this is
reported in the
