+=======================
+Speed Capabilities Test
+=======================
+
+The Speed Capabilities Test checks the speeds that the device lists and compares
+it to a user-defined set of expected speeds set in the ``speed_capabilities.cfg``.
+
+Prerequisites
+=============
+
+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
+
+Assuming that ports ``0`` and ``1`` of the test target are directly connected
+to the traffic generator, launch the ``testpmd`` application with the following
+arguments::
+
+  ./build/app/testpmd -- -i --portmask=0x3
+
+Start packet forwarding in the ``testpmd`` application with the ``start``
+command. Then, for each port on the target make the Traffic Generator
+transmit a packet to the port of arbitrary size less than the MTU of
+the target port, checking that the same amount of frames and bytes
+are received back by the Traffic Generator from the port.
+
+Ensure that the ``speed_capabilities.cfg`` file correctly reflects the speeds
+the device is expected to run at.
+
+
+Test Case : Speed Capabilities Test
+===================================
+
+1. Use testpmd to retrieve the speed information that the interface is linked at::
+
+      testpmd> show port info <PORT_ID>
+
+2. Compares the speed value against the rate in the speed_capabilities.cfg file.
+   The supported options for expected speeds are 1G, 10G, 25G, 40G, and 100G. Each interface must have an expected speed associated with it.
+   Example file below::
+
+      [suite]
+      expected_speeds={'interface1': '10G', 'interface2': '100M'}
+
+
+3. Verifies that the speeds matches accordingly.
+
+4. Repeats the verification for each NIC and interface found on the system.

+=======================
+Speed Capabilities Test
+=======================
+
+The Speed Capabilities Test checks the speeds that the device lists and compares
+it to a user-defined set of expected speeds set in the ``speed_capabilities.cfg``.
+
+Prerequisites
+=============
+
+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
+
+Assuming that ports ``0`` and ``1`` of the test target are directly connected
+to the traffic generator, launch the ``testpmd`` application with the following
+arguments::
+
+  ./build/app/testpmd -- -i --portmask=0x3
+
+Start packet forwarding in the ``testpmd`` application with the ``start``
+command. Then, for each port on the target make the Traffic Generator
+transmit a packet to the port of arbitrary size less than the MTU of
+the target port, checking that the same amount of frames and bytes
+are received back by the Traffic Generator from the port.
+
+Ensure that the ``speed_capabilities.cfg`` file correctly reflects the speeds
+the device is expected to run at.
+
+
+Test Case : Speed Capabilities Test
+===================================
+
+1. Use testpmd to retrieve the speed information that the interface is linked at::
+
+      testpmd> show port info <PORT_ID>
+
+2. Compares the speed value against the rate in the speed_capabilities.cfg file.
+   The supported options for expected speeds are 1G, 10G, 25G, 40G, and 100G. Each interface must have an expected speed associated with it.
+   Example file below::
+
+      [suite]
+      expected_speeds={'interface1': '10G', 'interface2': '100M'}
+
+
+3. Verifies that the speeds matches accordingly.
+
+4. Repeats the verification for each NIC and interface found on the system.

+=======================
+Speed Capabilities Test
+=======================
+
+The Speed Capabilities Test checks the speeds that the device lists and compares
+it to a user-defined set of expected speeds set in the ``speed_capabilities.cfg``.
+
+Prerequisites
+=============
+
+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
+
+Assuming that ports ``0`` and ``1`` of the test target are directly connected
+to the traffic generator, launch the ``testpmd`` application with the following
+arguments::
+
+  ./build/app/testpmd -- -i --portmask=0x3
+
+Start packet forwarding in the ``testpmd`` application with the ``start``
+command. Then, for each port on the target make the Traffic Generator
+transmit a packet to the port of arbitrary size less than the MTU of
+the target port, checking that the same amount of frames and bytes
+are received back by the Traffic Generator from the port.
+
+Ensure that the ``speed_capabilities.cfg`` file correctly reflects the speeds
+the device is expected to run at.
+
+
+Test Case : Speed Capabilities Test
+===================================
+
+1. Use testpmd to retrieve the speed information that the interface is linked at::
+
+      testpmd> show port info <PORT_ID>
+
+2. Compares the speed value against the rate in the speed_capabilities.cfg file.
+   The supported options for expected speeds are 1G, 10G, 25G, 40G, and 100G. Each interface must have an expected speed associated with it.
+   Example file below::
+
+      [suite]
+      expected_speeds={'interface1': '10G', 'interface2': '100M'}
+
+
+3. Verifies that the speeds matches accordingly.
+
+4. Repeats the verification for each NIC and interface found on the system.
