+MLX5 RegEx driver
+=================
+
+The MLX5 RegEx (Regular Expression) driver library
+(**librte_pmd_mlx5_regex**) provides support for **Mellanox BlueField 2**
+families of 25/50/100/200 Gb/s adapters.
+
+.. note::
+
+   Due to external dependencies, this driver is disabled in default
+   configuration of the "make" build. It can be enabled with
+   ``CONFIG_RTE_LIBRTE_MLX5_REGEX_PMD=y`` or by using "meson" build system which
+   will detect dependencies.
+
+
+Design
+------
+
+This PMD is configuring the RegEx HW engine.
+For the PMD to work, the application must supply
+a precompiled rule file in rof2 format.
+
+The PMD can use libibverbs and libmlx5 to access the device firmware
+or directly the hardware components.
+There are different levels of objects and bypassing abilities
+to get the best performances:
+
+- Verbs is a complete high-level generic API
+- Direct Verbs is a device-specific API
+- DevX allows to access firmware objects
+- Direct Rules manages flow steering at low-level hardware layer
+
+Enabling librte_pmd_mlx5_regex causes DPDK applications to be linked against
+libibverbs.
+
+A Mellanox mlx5 PCI device can be probed by either net/mlx5 driver or regex/mlx5
+driver but not in parallel. Hence, the user should decide the driver by dissabling
+the net device using ``CONFIG_RTE_LIBRTE_MLX5_PMD``.
+
+Supported NICs
+--------------
+
+* Mellanox\ |reg| BlueField 2 SmartNIC
+
+Prerequisites
+-------------
+
+- Mellanox OFED version: **5.0**
+  see :doc:`../../nics/mlx5` guide for more Mellanox OFED details.
+- Enable the RegEx caps using system call from the BlueField 2.
+  Contact Mellanox support for detail explanation.
+
+Compilation options
+~~~~~~~~~~~~~~~~~~~
+
+These options can be modified in the ``.config`` file.
+
+- ``CONFIG_RTE_LIBRTE_MLX5_REGEX_PMD`` (default **n**)
+
+  Toggle compilation of librte_pmd_mlx5 itself.
+
+- ``CONFIG_RTE_IBVERBS_LINK_DLOPEN`` (default **n**)
+
+  Build PMD with additional code to make it loadable without hard
+  dependencies on **libibverbs** nor **libmlx5**, which may not be installed
+  on the target system.
+
+  In this mode, their presence is still required for it to run properly,
+  however their absence won't prevent a DPDK application from starting (with
+  ``CONFIG_RTE_BUILD_SHARED_LIB`` disabled) and they won't show up as
+  missing with ``ldd(1)``.
+
+  It works by moving these dependencies to a purpose-built rdma-core "glue"
+  plug-in which must either be installed in a directory whose name is based
+  on ``CONFIG_RTE_EAL_PMD_PATH`` suffixed with ``-glue`` if set, or in a
+  standard location for the dynamic linker (e.g. ``/lib``) if left to the
+  default empty string (``""``).
+
+  This option has no performance impact.
+
+- ``CONFIG_RTE_IBVERBS_LINK_STATIC`` (default **n**)
+
+  Embed static flavor of the dependencies **libibverbs** and **libmlx5**
+  in the PMD shared library or the executable static binary.
+
+
+Run-time configuration
+~~~~~~~~~~~~~~~~~~~~~~
+
+- **ethtool** operations on related kernel interfaces also affect the PMD.
