* [dts] [PATCH V1]The Quota and Watermark sample application performs forwarding for each packet that is received on a given port, Internally, packets are pulled from the ports by the master logical core and put on a variable length processing pipeline, each stage of which being connected by rings. It is a test suite for this application.This commit move quota watermark test suite from internal fd11_dtf_merge branch to dts org master branch, add functional test case for basic work flow testing.

+Quota and Water-mark
+====================
+
+This document provides test plan for benchmarking of the Quota and Water-mark
+sample application. This is a simple example app featuring packet processing
+using Intel® Data Plane Development Kit (Intel® DPDK) that show-cases the use
+of a quota as the maximum number of packets enqueue/dequeue at a time and low
+and high water-marks to signal low and high ring usage respectively.
+Additionally, it shows how ring water-marks can be used to feedback congestion
+notifications to data producers by temporarily stopping processing overloaded
+rings and sending Ethernet flow control frames.
+
+
+Prerequisites
+-------------
+
+2x Intel® 82599 (Niantic) NICs (2x 10GbE full duplex optical ports per NIC)
+plugged into the available PCIe Gen2 8-lane slots in two different
+configurations:
+1. card0 and card1 attached to socket0.
+2. card0 attached to socket0 and card1 to socket1.
+
+Test cases
+----------
+
+The idea behind the testing process is to send a fixed number of frames from
+the traffic generator to the DUT while these are being forwarded back by the
+app and measure some of statistics. Those configurable parameters exposed by
+the control app will be modified to see how these affect into the app's
+performance.Functional test is only used for checking packet transfer flow with
+low watermark packets.
+
+The statistics to be measured are explained below.
+A table will be presented showing all the different permutations.
+
+
+- Ring size
+
+ - Size of the rings that interconnect two adjacent cores within the
+ pipeline.
+
+- Quota
+
+ - Value controls how many packets are being moved through the pipeline per
+ en-queue and de-queue.
+
+- Low water-mark
+
+ - Global threshold that will resume en-queuing on a ring once its usage
+ goes below it.
+
+- High water-mark
+
+ - Threshold that will stop en-queuing on rings for which the usage has it.
+
+- Frames sent
+
+ - Number of frames sent from the traffic generator.
+
+- Frames received
+
+ - Number of frames received on the traffic generator once they were
+ forwarded back by the app.
+
+- Control flow frames received
+
+ - Number of Control flow frames (PAUSE frame defined by the IEEE 802.3x
+ standard) received on the traffic generator TX port.
+
+- Transmit rate (Mpps)
+
+ - Rate of transmission. It is calculated dividing the number of sent
+ packets over the time it took the traffic generator to send them.
+
+
+ +-----------+-------+----------------+-----------------+-------------+-----------------+------------------------------+----------------------+
+ | Ring size | Quota | Low water-mark | High water-mark | Frames sent | Frames received | Control flow frames received | Transmit rate (Mpps) |
+ +===========+=======+================+=================+=============+=================+==============================+======================+
+ | 64 | 5 | 1 | 5 | 15000000 | | | |

+
+Test Case 1: Quota and Water-mark one socket (functional)
+==========================================
+Using No.1 card configuration.
+
+This test case calls the application using cores and ports masks similar to
+the ones shown below.
+
+- Core mask ``0xFF00``
+- Port mask ``0x280``
+
+This core mask will make use of eight physical cores within the same socket.
+The used ports belong to different NIC’s attached to the same socket.
+
+Sample command::
+
+ ./examples/quota_watermark/qw/build/qw -c 0xFF00 -n 4 -- -p 0x280
+
+After boot up qw and qwctl, send IP packets by scapy with low watermark value.
+Command format::
+ sendp([Ether()/IP()/("X"*26)]*<low watermark value>, iface="<port name>")
+
+Sample command::
+ sendp([Ether()/IP()/("X"*26)]*10, iface="p785p1")
+
+Test Case 2: Quota and Water-mark one socket (performance)
+==========================================
+
+This test case calls the application using cores and ports masks similar to
+the ones shown below.
+
+- Core mask ``0xFF00``
+- Port mask ``0x280``
+
+This core mask will make use of eight physical cores within the same socket.
+The used ports belong to different NIC’s attached to the same socket.
+
+Sample command::
+
+ ./examples/quota_watermark/qw/build/qw -c 0xFF00 -n 4 -- -p 0x280
+
+
+Test Case 3: Quota and Water-mark two sockets (performance)
+===========================================
+
+
+This test case calls the application using a core and port mask similar to the
+ones shown below.
+
+- Core mask ``0x0FF0``
+- Port mask ``0x202``
+
+This core mask will make use of eight physical cores; four within the first
+socket and four on the second one. The RX port will be attached to the first
+socket whereas the TX is to the second. This configuration will provoke the
+traffic going through the pipeline pass through the ``QPI`` channel.
+
+Sample command::
+
+ ./examples/quota_watermark/qw/build/qw -c 0x8180706 -n 4 -- -p 0x202
