[dts] [PATCH V2 1/2] ethtool_stats: upload test plan

[yufengmx <yufengx.mo@intel.com>]

Currently Ethtool supports a more complete list of stats for the same drivers
that DPDK supports. The idea behind this epic is two fold as following:
1. To achieve metric equivalence with what linux's ethtool provides.
2. To extend the functionality of the xstats API to enable the following options:
   ## the retrieval of aggregate stats upon request (Top level stats).
   ## the retrieval of the extended NIC stats.
   ## grouping of stats logically so they can be retrieved per logical grouping.
   ## the option to enable/disable the stats groups to retrieve similar to set
      private flags in ethtool.

+ethtool stats
+=============
+
+This document provides test plan for ethtool stats . This is a simple example
+app featuring packet processing, ethtool is a utility for Linux kernel-based
+operating system for displaying and modifying some parameters of network
+interface controllers (NICs) and their device drivers.
+
+Currently Ethtool supports a more complete list of stats for the same drivers
+that DPDK supports. The idea behind this epic is two fold as following.
+1. To achieve metric equivalence with what linux's ethtool provides.
+2. To extend the functionality of the xstats API to enable the following options::
+
+    - the retrieval of aggregate stats upon request (Top level stats).
+    - the retrieval of the extended NIC stats.
+    - grouping of stats logically so they can be retrieved per logical grouping.
+    - the option to enable/disable the stats groups to retrieve similar to set private flags in ethtool.
+
+Prerequisites
+=============
+
+2xNICs (2 full duplex optical ports per NIC). One on dut, another one on tester,
+link them together. Update two nics' firmware to latest version.
+
+Test cases
+==========
+
+Check port extended statistics parameter after sending packet from peer link port.
+
+bind two ports::
+
+    ./usertools/dpdk-devbind.py --bind=igb_uio <pci address 1> <pci address 2>
+
+Test Case: xstat command set intergrity
+---------------------------------------
+
+check ``dpdk-procinfo`` tool support ``xstats`` command options.
+
+These options should be included::
+
+   ``xstats``
+   ``xstats-name``
+   ``xstats-id``
+   ``xstats-reset``
+
+steps:
+
+#. boot up ``testpmd``::
+
+    ./<target name>/app/testpmd -c 0x600006 -n 4  -- -i --port-topology=loop
+
+#. run ``dpdk-procinfo`` tool::
+
+    ./<target name>/app/dpdk-procinfo
+
+#. check ``dpdk-procinfo`` tool output should contain upper options.
+
+Test Case: xstat command
+------------------------
+
+check if port extended statistics can get right data.
+
+steps:
+
+#. boot up ``testpmd``::
+
+    ./<target name>/app/testpmd -c 0x600006 -n 4  -- -i --port-topology=loop
+
+#. send udp packet of 64/72/128/256/512/1024 size to port 0/1::
+
+    sendp([Ether()/IP()/UDP()/Raw('\0'*60)], iface=<port 0 name>)
+
+#. run ``dpdk-procinfo`` tool with ``xstats`` option and check if all port have
+   a correct data of different size packet::
+
+    ./<target name>/app/dpdk-procinfo -- -p 3 --xstats
+
+Test Case: xstat-reset command
+------------------------------
+
+check if port extended statistics can be cleared.
+
+steps:
+
+#. boot up ``testpmd``::
+
+    ./<target name>/app/testpmd -c 0x600006 -n 4  -- -i --port-topology=loop
+
+#. send udp packet of 64/72/128/256/512/1024 size to port 0/1::
+
+    sendp([Ether()/IP()/UDP()/Raw('\0'*60)], iface=<port 0 name>)
+
+#. run ``dpdk-procinfo`` tool with ``xstats-reset`` option and check if all port
+   statistics have been cleared::
+
+    ./<target name>/app/dpdk-procinfo -- -p 3 --xstats-reset
+
+Test Case: xstat single statistic
+---------------------------------
+
+check if port extended statistic name can be get by statistic id and check
+related data's correctness.
+
+steps:
+
+#. boot up ``testpmd``::
+
+    ./<target name>/app/testpmd -c 0x600006 -n 4  -- -i --port-topology=loop
+
+#. run ``dpdk-procinfo`` tool with ``xstats`` option to get all NIC extended
+   statistics parameters of port and use the output display sequence as parameter
+   index in the following search index::
+
+    ./<target name>/app/dpdk-procinfo -- -p 3 --xstats
+
+#. send udp packet of 64/72/128/256/512/1024 size to port 0/1::
+
+    sendp([Ether()/IP()/UDP()/Raw('\0'*60)], iface=<port 0 name>)
+
+#. run ``dpdk-procinfo`` tool with ``xstats-id`` option to get the statistic
+   name corresponding with the index id::
+
+    ./<target name>/app/dpdk-procinfo -- -p 3 --xstats-id 0,1,...N
+
+#. run ``dpdk-procinfo`` tool with ``xstats-name`` option to get the statistic
+   data corresponding with the statistic name::
+
+    ./<target name>/app/dpdk-procinfo -- -p 3 --xstats-name <statistic name>
