+Marvell NITROX Compression Poll Mode Driver
+===========================================
+
+The Nitrox compression poll mode driver provides support for offloading
+compression and decompression operations to the NITROX V processor.
+Detailed information about the NITROX V processor can be obtained here:
+
+* https://www.marvell.com/security-solutions/nitrox-security-processors/nitrox-v/
+
+Features
+--------
+
+NITROX V compression PMD has support for:
+
+Compression/Decompression algorithm:
+
+* DEFLATE
+
+Huffman code type:
+
+* FIXED
+* DYNAMIC
+
+Window size support:
+
+* Min - 2 bytes
+* Max - 32KB
+
+Checksum generation:
+
+* CRC32, Adler
+
+Limitations
+-----------
+
+* Compressdev level 0, no compression, is not supported.
+
+Initialization
+--------------
+
+Nitrox compression PMD depends on Nitrox kernel PF driver being installed on
+the platform. Nitrox PF driver is required to create VF devices which will
+be used by the PMD. Each VF device can enable one compressdev PMD.
+
+Nitrox kernel PF driver is available as part of CNN55XX-Driver SDK. The SDK
+and it's installation instructions can be obtained from:
+`Marvell Customer Portal <https://www.marvell.com/support/extranets.html>`_.
