[DTS][PATCH V1 0/3] add new test suite ice_config_port_speed

[Jin Ling]

This suite provides the function for configuring the port speed function in testpmd
You can get the link speed supported of the NIC by executing `ethtool <iface>`, only the supported speed can be configured,
if its' link partner also supports this speed, then once the speed of the dut is reconfigured,
the link partner's speed will also be configured.

+ICE Config Port Speed Tests
+===========================
+
+Description
+===========
+
+This document provides the testplan for configuring the port speed function in testpmd
+You can get the link speed supported of the NIC by executing `ethtool <iface>`, only the supported speed can be configured,
+if its' link partner also supports this speed, then once the speed of the dut is reconfigured, the link partner's speed will also be configured
+
+
+Prerequisites
+=============
+
+topology
+--------
+
+dut_port_0 <-----------> tester_port_0
+
+
+Hardware
+--------
+
+Supported NICs: columbiaville_25g/columbiaville_100g
+
+Software
+--------
+
+dpdk: http://dpdk.org/git/dpdk
+scapy: http://www.secdev.org/projects/scapy/
+
+General set up
+--------------
+
+1. Compile DPDK::
+
+    CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib --default-library=static x86_64-native-linuxapp-gcc
+    ninja -C x86_64-native-linuxapp-gcc -j 110
+
+2. Get the pci device id of DUT, for example::
+
+    ./usertools/dpdk-devbind.py -s
+
+    0000:31:00.0 'Device 159b' if=ens4 drv=ice unused=vfio-pci
+
+3. Get the supported speed of dut and tester::
+
+    Dut::
+        ethtool ens785f0:
+        Settings for ens785f0:
+        Supported ports: [ FIBRE ]
+        Supported link modes:   1000baseT/Full
+                                10000baseT/Full
+                                25000baseCR/Full
+                                25000baseSR/Full
+                                1000baseX/Full
+                                10000baseSR/Full
+                                10000baseLR/Full
+        Supported pause frame use: Symmetric
+        Supports auto-negotiation: Yes
+        Supported FEC modes: None
+        Advertised link modes:  1000baseX/Full
+                                10000baseSR/Full
+
+    tester::
+        ethtool ens260f0
+        Settings for ens260f0:
+        Supported ports: [ FIBRE ]
+        Supported link modes:   1000baseX/Full
+                                10000baseSR/Full
+        Supported pause frame use: Symmetric Receive-only
+        Supports auto-negotiation: Yes
+        Supported FEC modes: Not reported
+        Advertised link modes:  1000baseX/Full
+                                10000baseSR/Full
+        Advertised pause frame use: No
+        Advertised auto-negotiation: Yes
+
+    Notice that the link speed of dut cannot be configured when dut is `link down`,
+    so if dut is `link up` , only `Advertised link modes` can be cofigured.
+
+
+Test case 1: port config link speed
+-------------------------------------
+
+In this test case, use `port config <port_id> speed 10|100|1000|10000|25000|40000|50000|100000|200000|400000|auto duplex half|full|auto`
+to set port speed, then use `show port info <port_id>` can see the new speed and duplex.
+
+test steps
+~~~~~~~~~~
+1. launch testpmd::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c f -n 4 -a 31:00.0 -- -i
+
+2. make sure that the link status of dut is up::
+
+    testpmd> show port info 0
+    ********************* Infos for port 0  *********************
+    MAC address: B4:96:91:BB:64:D8
+    Device name: 31:00.0
+    Driver name: net_ice
+    Firmware-version: 4.20 0x8001642c 1.3341.0
+    Devargs:
+    Connect to socket: 0
+    memory allocation on the socket: 0
+    *Link status: up
+    Link speed: 100 Gbps*
+    Link duplex: full-duplex
+    Autoneg status: On
+
+3. stop all ports and set new speed::
+
+    testpmd> port stop all
+    testpmd> port config 0 speed 1000|100000 duplex full
+    testpmd> port start all
+
+Expected result
+~~~~~~~~~~~~~~~
+
+    1. Check that the speed has been changed::
+
+        testpmd> show port info all
+
+        ********************* Infos for port 0  *********************
+        ...
+        Link speed: 10 Gbps
+        Link duplex: full-duplex
+        ...
+
+    2. check tester's has been changed if it supports this spped::
+
+        ethtool ens10:
+        Settings for ens10:
+            ...
+            Speed: 10000Mb/s
+            Duplex: Full
+            ...
