+MANA poll mode driver library
+=============================
+
+The MANA poll mode driver library (**librte_net_mana**) implements support
+for Microsoft Azure Network Adapter VF in SR-IOV context.
+
+Features
+--------
+
+Features of the MANA Ethdev PMD are:
+
+Prerequisites
+-------------
+
+This driver relies on external libraries and kernel drivers for resources
+allocations and initialization. The following dependencies are not part of
+DPDK and must be installed separately:
+
+- **libibverbs** (provided by rdma-core package)
+
+  User space verbs framework used by librte_net_mana. This library provides
+  a generic interface between the kernel and low-level user space drivers
+  such as libmana.
+
+  It allows slow and privileged operations (context initialization, hardware
+  resources allocations) to be managed by the kernel and fast operations to
+  never leave user space. The minimum required rdma-core version is v43.
+
+- **libmana** (provided by rdma-core package)
+
+  Low-level user space driver library for Microsoft Azure Network Adapter
+  devices, it is automatically loaded by libibverbs. The minimum required
+  version of rdma-core with libmana is v43.
+
+- **Kernel modules**
+
+  They provide the kernel-side verbs API and low level device drivers that
+  manage actual hardware initialization and resources sharing with user
+  space processes. The minimum required Linux kernel version is 6.1.
+
+  Unlike most other PMDs, these modules must remain loaded and bound to
+  their devices:
+
+  - mana: Ethernet device driver that provides kernel network interfaces.
+  - mana_ib: InifiniBand device driver.
+  - ib_uverbs: user space driver for verbs (entry point for libibverbs).
+
+Driver compilation and testing
+------------------------------
+
+Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+for details.
+
+MANA PMD arguments
+--------------------
+
+The user can specify below argument in devargs.
+
+#.  ``mac``:
+
+    Specify the MAC address for this device. If it is set, the driver
+    probes and loads the NIC with a matching mac address. If it is not
+    set, the driver probes on all the NICs on the PCI device. The default
+    value is not set, meaning all the NICs will be probed and loaded.
+    User can specify multiple mac=xx:xx:xx:xx:xx:xx arguments for up to
+    8 NICs.
