[PATCH v1 00/24] vfio-user client

[John Johnson]

Hello,

This is the 6th revision of the vfio-user client implementation.
It is the first patch series (the previous revisions were RFCs)

First of all, thank you for your time reviewing the RFC versions.

The vfio-user framework consists of 3 parts:
 1) The VFIO user protocol specification.
 2) A client - the VFIO device in QEMU that encapsulates VFIO messages
    and sends them to the server.
 3) A server - a remote process that emulates a device.

This patchset implements parts 1 and 2.

The libvfio-user project (https://github.com/nutanix/libvfio-user)
can be used by a remote process to handle the protocol to implement the third 
part.
We also have upstreamed a patch series that implement a server using QEMU.
