From: Leon Romanovsky <leonro at nvidia.com> Changelog: v1: * Renamed _mlx5_rescan_driver to be mlx5_rescan_driver_locked like in other parts of the mlx5 driver. * Renamed MLX5_INTERFACE_PROTOCOL_VDPA to tbe MLX5_INTERFACE_PROTOCOL_VNET as a preparation to coming series from Eli C. * Some small naming renames in mlx5_vdpa. * Refactored adev index code to make Parav's SF series

This patch series is based on Eugenio's fix for handling CVQs in a different ASID [0]. The first patch is the actual fix. The next 2 patches are fixing a possible issue that I found while implementing patch 1. The patches are ordered like this for clarity.

In order to reduce needlessly high setup and teardown cost of iotlb mapping during live migration, it's crucial to decouple the vhost-vdpa iotlb abstraction from the virtio device life cycle, i.e. iotlb mappings should be left intact across virtio device reset [1]. For it to work, the on-chip IOMMU parent device should implement a separate .reset_map() operation callback to restore 1:1 DMA
