Sure, will do, thanks!
IMHO, I think this transport vq series focus on introducing a new virtio transport layer for hyper scaling, like SIOV. And the admin vq proposal looks focusing on administration, to control the sub-devices. so maybe the transport vq and the admin vq are works in parallel.I would like to see whether we can unify this with the admin queue work somehow. The technology is different (SIOV vs SRIOV) but there are also similarities. Do you care to review some patches from the admin queue proposals maybe?
This series also defines a commands set over the transport virtqueue, including: The command to query available resources of the management device The commands to create / destroy the managed devices. The commands to config the managed devices. The commands to config virtqueues of the managed devices.
