+ZXDH Poll Mode Driver
+======================
+
+The ZXDH PMD (**librte_net_zxdh**) provides poll mode driver support
+for 25/100 Gbps ZXDH NX Series Ethernet Controller based on
+the ZTE Ethernet Controller E310/E312.
+
+
+Features
+--------
+
+Features of the zxdh PMD are:
+
+- Multi arch support: x86_64, ARMv8.
+- Multiple queues for TX and RX
+- Receiver Side Scaling (RSS)
+- MAC/VLAN filtering
+- Checksum offload
+- TSO offload
+- VLAN/QinQ stripping and inserting
+- Promiscuous mode
+- Port hardware statistics
+- Link state information
+- Link flow control
+- Scattered and gather for TX and RX
+- SR-IOV VF
+- VLAN filter and VLAN offload
+- Allmulticast mode
+- MTU update
+- Jumbo frames
+- Unicast MAC filter
+- Multicast MAC filter
+- Flow API
+- Set Link down or up
+- FW version
+- LRO
+
+Prerequisites
+-------------
+
+This PMD driver need NPSDK library for system initialization and allocation of resources.
+Communication between PMD and kernel modules is mediated by zxdh Kernel modules.
+The NPSDK library and zxdh Kernel modules are not part of DPDK and must be installed
+separately:
+
+- Getting the latest NPSDK library and software supports using
+  ``_.
+
+Driver compilation and testing
+------------------------------
+
+Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+for details.
+
+Limitations or Known issues
+---------------------------
+X86-32, Power8, ARMv7 and BSD are not supported yet.
