 =======================
 
-The mlx5 vDPA (vhost data path acceleration) driver library
-(**librte_vdpa_mlx5**) provides support for **NVIDIA ConnectX-6**,
-**NVIDIA ConnectX-6 Dx**, **NVIDIA ConnectX-6 Lx**, **NVIDIA ConnectX7**,
-**NVIDIA BlueField**, **NVIDIA BlueField-2** and **NVIDIA BlueField-3** families
-of 10/25/40/50/100/200 Gb/s adapters as well as their virtual functions (VF) in
-SR-IOV context.

-.. note::
-
-   This driver is enabled automatically when using "meson" build system which
-   will detect dependencies.
+The mlx5 vDPA (vhost data path acceleration) driver (``librte_vdpa_mlx5``)
+provides support for NVIDIA NIC and DPU device families.
 
 See :doc:`../../platform/mlx5` guide for design details,
 and which PMDs can be combined with vDPA PMD.

 Error handling
-^^^^^^^^^^^^^^
+--------------
 
 Upon potential hardware errors, mlx5 PMD try to recover, give up if failed 3
 times in 3 seconds, virtq will be put in disable state. User should check log
 to get error information, or query vdpa statistics counter to know error type
 and count report.

 Statistics
-^^^^^^^^^^

 The device statistics counter persists in reconfiguration until the device gets
 removed. User can reset counters by calling function rte_vdpa_reset_stats().
