-Sample Application Tests: 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.
-
-

-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
