+NTNIC Poll Mode Driver
+======================
+
+The NTNIC PMD provides poll mode driver support for Napatech smartNICs.
+
+
+Design
+------
+
+The NTNIC PMD is designed as a pure user-space driver, and requires no special
+Napatech kernel modules.
+
+The Napatech smartNIC presents one control PCI device (PF0). NTNIC PMD accesses
+smartNIC PF0 via vfio-pci kernel driver. Access to PF0 for all purposes is
+exclusive, so only one process should access it. The physical ports are located
+behind PF0 as DPDK port 0 and 1.
+
+
+Supported NICs
+--------------
+
+- NT200A02 2x100G SmartNIC
+
+ - FPGA ID 9563 (Inline Flow Management)
+
+All information about NT200A02 can be found by link below:
+https://www.napatech.com/products/nt200a02-smartnic-inline/
+
+Limitations
+~~~~~~~~~~~
+
+Kernel versions before 5.7 are not supported. Kernel version 5.7 added vfio-pci
+support for creating VFs from the PF which is required for the PMD to use
+vfio-pci on the PF. This support has been back-ported to older Linux
+distributions and they are also supported. If vfio-pci is not required kernel
+version 4.18 is supported.
