+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 uses 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
+
+Enabling librte_pmd_mlx5_regex causes DPDK applications to be linked against
+libibverbs.
+
+Mellanox mlx5 PCI device can be probed by number of different pci devices, for example
+net / vDPA / RegEx. To select the RegEx PMD ``class=regex`` should be specified
+as device parameter.
+
+Supported NICs
+--------------
+
+* Mellanox\ |reg| BlueField 2 SmartNIC
+
+Prerequisites
+-------------
+
+- BlueField 2 running Mellonx supported kernel.
+- Enable the RegEx caps using system call from the BlueField 2.
+- Official support is not yet released.
+
+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.
+
+
+Run-time configuration
+~~~~~~~~~~~~~~~~~~~~~~
+
+- **ethtool** operations on related kernel interfaces also affect the PMD.
