7de66d823e vdpa/mlx5: support virtio queue statistics get
Add support for statistics operations.

A DevX counter object is allocated per virtq in order to
manage the virtq statistics.

The counter object is allocated before the virtq creation
and destroyed after it, so the statistics are valid only in
the life time of the virtq.

1cb4415751 vhost: introduce operation to get vDPA queue stats
The vDPA device offloads all the datapath of the vhost
device to the HW device.

In order to expose to the user traffic information this
patch introduces new 3 APIs to get traffic statistics, the
device statistics name and to reset the statistics per
virtio queue.

The statistics are taken directly from the vDPA driver
managing the HW device and can be different for each vendor
driver.

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.
