I would assume that if regular PCI hotplug works (with igb_uio), then so would hotplug with VFIO, as it basically utilizes the same PCI infrastructure igb_uio does. That said, I'm not aware of any patches submitted that had to do with VFIO and hotplug, so I guess the answer is, not at the moment.

I was asking as the documentation explicitly mentions its not supported.
http://dpdk.org/doc/guides/prog_guide/port_hotplug_framework.html#hotplug
- "To detach a port, the port should be backed by a device that igb_uio
manages. VFIO is not supported."
I could not find any specific reason why it's not supported, so if some
one can explain this it would help also...
Cheers,
Eelco
