+======================
+IP fragmentation Tests
+======================
+
+The IP fragmentation results are produced using ''ip_fragmentation'' application.
+The test application should run with both IPv4 and IPv6 fragmentation.
+
+The suit support NIC: Intel® Ethernet 700 Series, Intel® Ethernet 800 Series, 82599 and igc driver NIC.
+
+Prerequisites
+=============
+
+1. Hardware requirements:
+
+   - For each CPU socket, each memory channel should be populated with at least 1x DIMM
+   - Board is populated with at least 2x 1GbE or 10GbE ports. Special PCIe restrictions may
+     be required for performance. For example, the following requirements should be
+     met for Intel 82599 NICs:
+
+       - NICs are plugged into PCIe Gen2 or Gen3 slots
+       - For PCIe Gen2 slots, the number of lanes should be 8x or higher
+       - A single port from each NIC should be used, so for 2x ports, 2x NICs should
+         be used
+
+   - NIC ports connected to traffic generator. It is assumed that the NIC ports
+     P0, P1, P2, P3 (as identified by the DPDK application) are connected to the
+     traffic generator ports TG0, TG1, TG2, TG3. The application-side port mask of
+     NIC ports P0, P1, P2, P3 is noted as PORTMASK in this section.
+     Traffic generator should support sending jumbo frames with size up to 9K.
+
+2. BIOS requirements:
+
+   - Intel Hyper-Threading Technology is ENABLED
+   - Hardware Prefetcher is DISABLED
+   - Adjacent Cache Line Prefetch is DISABLED
+   - Direct Cache Access is DISABLED
+
+3. Linux kernel requirements:
+
+   - Linux kernel has the following features enabled: huge page support, UIO, HPET
+   - Appropriate number of huge pages are reserved at kernel boot time
+   - The IDs of the hardware threads (logical cores) per each CPU socket can be
+     determined by parsing the file /proc/cpuinfo. The naming convention for the
+     logical cores is: C{x.y.z} = hyper-thread z of physical core y of CPU socket x,
+     with typical values of x = 0 .. 3, y = 0 .. 7, z = 0 .. 1. Logical cores
+     C{0.0.1} and C{0.0.1} should be avoided while executing the test, as they are
+     used by the Linux kernel for running regular processes.
+
+4. Software application requirements
+
+5. If using vfio the kernel must be >= 3.6+ and VT-d must be enabled in bios.When
+   using vfio, use the following commands to load the vfio driver and bind it
+   to the device under test::
+
+      modprobe vfio
+      modprobe vfio-pci
+      usertools/dpdk-devbind.py --bind=vfio-pci device_bus_id
+
+   - The test can be run with IPv4 package. The LPM table used for IPv4 packet routing is:
+
+   +-------+-------------------------------------+-----------+
+   |Entry #|LPM prefix (IP/length)               |Output port|
+   +-------+-------------------------------------+-----------+
+   |   0   |   100.10.0.0/16                     |     P2    |
+   +-------+-------------------------------------+-----------+
+   |   1   |   100.20.0.0/16                     |     P2    |
+   +-------+-------------------------------------+-----------+
+   |   2   |   100.30.0.0/16                     |     P0    |
+   +-------+-------------------------------------+-----------+
+   |   3   |   100.40.0.0/16                     |     P0    |
+   +-------+-------------------------------------+-----------+
+
+
+   - The test can be run with IPv6 package, which follows rules below.
+
+    - There is no support for Hop-by-Hop or Routing extension headers in the packet
+      to be fragmented. All other optional headers, which are not part of the
+      unfragmentable part of the IPv6 packet are supported.
+
+    - When a fragment is generated, its identification field in the IPv6
+      fragmentation extension header is set to 0. This is not RFC compliant, but
+      proper identification number generation is out of the scope of the application
+      and routers in an IPv6 path are not allowed to fragment in the first place...
+      Generating that identification number is the job of a proper IP stack.
+
+   - The LPM table used for IPv6 packet routing is:
+
+   +-------+-------------------------------------+-----------+
+   |Entry #|LPM prefix (IP/length)               |Output port|
+   +-------+-------------------------------------+-----------+
+   |   0   |   101:101:101:101:101:101:101:101/48|     P2    |
+   +-------+-------------------------------------+-----------+
+   |   1   |   201:101:101:101:101:101:101:101/48|     P2    |
+   +-------+-------------------------------------+-----------+
+   |   2   |   301:101:101:101:101:101:101:101/48|     P0    |
+   +-------+-------------------------------------+-----------+
+   |   3   |   401:101:101:101:101:101:101:101/48|     P0    |
+   +-------+-------------------------------------+-----------+
+
+   The following items are configured through the command line interface of the application:
+
+     - The set of one or several RX queues to be enabled for each NIC port
+     - The set of logical cores to execute the packet forwarding task
+     - Mapping of the NIC RX queues to logical cores handling them.
+
+6. Compile examples/ip_fragmentation::
+
+    meson configure -Dexamples=ip_fragmentation x86_64-native-linuxapp-gcc
+    ninja -C x86_64-native-linuxapp-gcc
+
+Test Case 1: Throughput test
+============================
+
+The test report should provide the throughput rate measurements (in mpps and % of the line rate for 2x NIC ports)
+for the following input frame sizes: 64 bytes, 1518 bytes, 1519 bytes, 2K, 9k.
