[Qemu-devel] [PATCH v7 2/4] vfio: VFIO driver for mediated devices

VFIO MDEV driver registers with MDEV core driver. MDEV core driver creates mediated device and calls probe routine of MPCI VFIO driver. This driver adds mediated device to VFIO core module. Main aim of this module is to manage all VFIO APIs for each mediated device. Those are: - get VFIO device
