95276abaaf vdpa/mlx5: introduce Mellanox vDPA driver
Add a new driver to support vDPA operations by Mellanox devices.

The first Mellanox devices which support vDPA operations are
ConnectX-6 Dx and Bluefield1 HCA for their PF ports and VF ports.

This driver is depending on rdma-core like the mlx5 PMD, also it is
going to use mlx5 DevX to create HW objects directly by the FW.
Hence, the common/mlx5 library is linked to the mlx5_vdpa driver.

This driver will not be compiled by default due to the above
dependencies.

Register a new log type for this driver.

3df349b7af drivers: introduce vDPA class
The vDPA (vhost data path acceleration) drivers provide support for
the vDPA operations introduced by the rte_vhost library.

Any driver which provides the vDPA operations should be moved\added to
the vdpa class under drivers/vdpa/.

Create the general files for vDPA class in drivers and in documentation.

The management tree for vDPA drivers is
git://dpdk.org/next/dpdk-next-virtio.
