-Kernel NIC Interface (KNI) Tests
-================================
-
-Description
-===========
-
-This document provides the plan for testing the Kernel NIC Interface
-application with support of rte_kni kernel module.
-Kernel NIC Interface is a DPDK alternative solution to the existing linux
-tun-tap interface for the exception path. Kernel NIC Interface allows the
-standard Linux net tools(ethtool/ifconfig/tcpdump) to facilitate managing the
-DPDK port. At the same time, it add an interface with the kernel net stack.
-The test supports Multi-Thread KNI.
-
-All kni model parameter detail info on user guides:http://dpdk.org/doc/guides/sample_app_ug/kernel_nic_interface.html
-
-The ``rte_kni`` kernel module can be installed by a ``lo_mode`` parameter.
-
-loopback disabled::
-
- insmod rte_kni.ko
- insmod rte_kni.ko "lo_mode=lo_mode_none"
- insmod rte_kni.ko "lo_mode=unsupported string"
-
-loopback mode=lo_mode_ring enabled::
-
- insmod rte_kni.ko "lo_mode=lo_mode_ring"
-
-loopback mode=lo_mode_ring_skb enabled::
-
- insmod rte_kni.ko "lo_mode=lo_mode_ring_skb"
-
-The ``rte_kni`` kernel module can also be installed by a ``kthread_mode``
-parameter. This parameter is ``single`` by default.
-
-kthread single::
-
- insmod rte_kni.ko
- insmod rte_kni.ko "kthread_mode=single"
-
-kthread multiple::
-
- insmod rte_kni.ko
- insmod rte_kni.ko "kthread_mode=multiple"
-
-
-The ``kni`` application is run with EAL parameters and parameters for the
-application itself. For details about the EAL parameters, see the relevant
-DPDK **Getting Started Guide**. This application supports two parameters for
-itself.
-
-- ``--config="(port id, rx lcore, tx lcore, kthread lcore, kthread lcore, ...)"``:
- Port and cores selection. Kernel threads are ignored if ``kthread_mode``
- is not ``multiple``.
-
-ports cores::
-
- e.g.:
-
- --config="(0,1,2),(1,3,4)" No kernel thread specified.
- --config="(0,1,2,21),(1,3,4,23)" One kernel thread in use.
- --config="(0,1,2,21,22),(1,3,4,23,25) Two kernel threads in use.
-
-- ``-P``: Promiscuous mode. This is off by default.
-
-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
-
-The DUT has at least 2 DPDK supported IXGBE/I40E/ICE/IGC NIC ports.
-
-The DUT has to be able to install rte_kni kernel module and launch kni
-application with a default configuration (This configuration may change form a
-system to another)::
-
- rmmod rte_kni
- rmmod igb_uio
- insmod ./x86_64-default-linuxapp-gcc/kmod/igb_uio.ko
- insmod ./x86_64-default-linuxapp-gcc/kmod/rte_kni.ko
- ./<build_target>/examples/dpdk-kni -c 0xa0001e -n 4 -- -P -p 0x3 --config="(0,1,2,21),(1,3,4,23)" &
-
-Case config::
-
- For enable KNI features, need build DPDK with '-Denable_kmods=True'.
-
-Test Case: ifconfig testing
-===========================
-
-Launch the KNI application. Assume that ``port 2 and 3`` are used to this
-application. Cores 1 and 2 are used to read from NIC, cores 2 and 4 are used
-to write to NIC, threads 21 and 23 are used by the kernel.
-
-As the kernel module is installed using ``"kthread_mode=single"`` the core
-affinity is set using ``taskset``::
-
- ./<build_target>/examples/dpdk-kni -c 0xa0001e -n 4 -- -P -p 0xc --config="(2,1,2,21),(3,3,4,23)"
-
-
-Verify whether the interface has been added::
-
- ifconfig -a
-
-
-If the application is launched successfully, it will add two interfaces in
-kernel net stack named ``vEth2_0``, ``vEth3_0``.
-
-Interface name start with ``vEth`` followed by the port number and an
-additional incremental number depending on the number of kernel threads::
-
- vEth2_0: flags=4098<BROADCAST,MULTICAST> mtu 1500
- ether 00:00:00:00:00:00 txqueuelen 1000 (Ethernet)
- RX packets 14 bytes 2098 (2.0 KiB)
- RX errors 0 dropped 10 overruns 0 frame 0
- TX packets 0 bytes 0 (0.0 B)
- TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
-
- vEth3_0: flags=4098<BROADCAST,MULTICAST> mtu 1500
- ether 00:00:00:00:00:00 txqueuelen 1000 (Ethernet)
- RX packets 13 bytes 1756 (1.7 KiB)
- RX errors 0 dropped 10 overruns 0 frame 0
- TX packets 0 bytes 0 (0.0 B)
- TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
-
-
-
-Verify whether ifconfig can set Kernel NIC Interface up::
-
- ifconfig vEth2_0 up
-
-Now ``vEth2_0`` is up and has IPv6 address::
-
- vEth2_0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
- inet6 fe80::92e2:baff:fe37:92f8 prefixlen 64 scopeid 0x20<link>
- ether 90:e2:ba:37:92:f8 txqueuelen 1000 (Ethernet)
- RX packets 30 bytes 4611 (4.5 KiB)
- RX errors 0 dropped 21 overruns 0 frame 0
- TX packets 6 bytes 468 (468.0 B)
- TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
-
-
-Verify whether ifconfig can add an ipv6 address::
-
- ifconfig vEth2_0 add fe80::1
-
-``vEth2_0`` has added ipv6 address::
-
- 29: vEth2_0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
- inet6 fe80::1/128 scope link
- valid_lft forever preferred_lft forever
- inet6 fe80::92e2:baff:fe37:92f8/64 scope link
- valid_lft forever preferred_lft forever
-
-
-Delete the IPv6 address::
-
- ifconfig vEth2_0 del fe80::1
-
-The port deletes it::
-
- 29: vEth2_0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
- inet6 fe80::92e2:baff:fe37:92f8/64 scope link
- valid_lft forever preferred_lft forever
-
-Set MTU parameter::
-
- ifconfig vEth2_0 mtu 1300
-
-``vEth2_0`` changes the mtu parameter::
-
- 29: vEth2_0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1300 qdisc pfifo_fast state UNKNOWN mode DEFAULT qlen 1000
- link/ether 90:e2:ba:37:92:f8 brd ff:ff:ff:ff:ff:ff
-
-Verify whether ifconfig can set ip address::
-
- ifconfig vEth2_0 192.168.2.1 netmask 255.255.255.192
- ip -family inet address show dev vEth2_0
-
-``vEth2_0`` has IP address and netmask now::
-
- 29: vEth2_0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1300 qdisc pfifo_fast state UNKNOWN qlen 1000
- inet 192.168.2.1/26 brd 192.168.2.63 scope global vEth2_0
-
-Verify whether ifconfig can set ``vEth2_0`` down::
-
- ifconfig vEth2_0 down
- ifconfig vEth2_0
-
-``vEth2_0`` is down and no ipv6 address::
-
- vEth2_0: flags=4098<BROADCAST,MULTICAST> mtu 1300
- inet 192.168.2.1 netmask 255.255.255.192 broadcast 192.168.2.63
- ether 90:e2:ba:37:92:f8 txqueuelen 1000 (Ethernet)
- RX packets 70 bytes 12373 (12.0 KiB)
- RX errors 0 dropped 43 overruns 0 frame 0
- TX packets 25 bytes 4132 (4.0 KiB)
- TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
-
-
-Repeat all the steps for interface ``vEth3_0``
-
-Test Case: Ping and Ping6 testing
-=================================
-
-If the application is launched successfully, it will add two interfaces in
-kernel net stack named ``vEth2_0``, ``vEth3_0``.
-
-Assume the link status of ``vEth2_0`` is up and set ip address is ``192.168.2.1``
-and ``vEth3_0`` is up and set ip address is ``192.168.3.1``. Verify the

-
-Repeat all the steps for interface ``vEth3_0``
-
-Test Case: Tcpdump testing
-==========================
-
-Assume ``port A and B`` on packet generator connects to NIC ``port 2 and 3``.
-Trigger the packet generator of bursting packets from ``port A and B`, then
-check if tcpdump can capture all packets. The packets should include
-``tcp`` packets, ``udp`` packets, ``icmp`` packets, ``ip`` packets,
-``ether+vlan tag+ip`` packets, ``ether`` packets.
-
-Verify whether tcpdump can capture packets::
-
- tcpdump -i vEth2_0
- tcpdump -i vEth3_0
-
-
-Test Case: Ethtool testing
-==========================
-
-In this time, KNI can only support ethtool commands which is to get information.
-So all below commands are to show information commands.
-

-
-Verify whether ethtool can show Kernel NIC Interface's RX/TX ring parameters::
-
- ethtool -g vEth2_0
-
-Verify whether ethtool can show Kernel NIC Interface's Coalesce parameters.
-It is not currently supported::
-
- ethtool -c vEth2_0
-
-Verify whether ethtool can show Kernel NIC Interface's MAC registers::
-
- ethtool -d vEth2_0
-
-Verify whether ethtool can show Kernel NIC Interface's EEPROM dump::
-
- ethtool -e vEth2_0
-
-Repeat all the steps for interface ``vEth3_0``
-
-Test Case: Packets statistics testing
-=====================================
-
-Install the kernel module with loopback parameter ``lo_mode=lo_mode_ring_skb``
-and launch the KNI application.
-
-Assume that ``port 2 and 3`` are used by this application::
-
- rmmod kni
- insmod ./kmod/rte_kni.ko "lo_mode=lo_mode_ring_skb"
- ./<build_target>/examples/dpdk-kni -c 0xff -n 3 -- -p 0xf -i 0xf -o 0xf0
-
-Assume ``port A and B`` on tester connects to NIC ``port 2 and 3``.
-
-Get the RX packets count and TX packets count::
-
- ifconfig vEth2_0
-
-Send 5 packets from tester. And check whether both RX and TX packets of
-``vEth2_0`` have increased 5.
-
-Repeat for interface ``vEth3_0``
-
-Test Case: Stress testing
-=========================
-
-Insert the rte_kni kernel module 50 times while changing the parameters.
-Iterate through lo_mode and kthread_mode values sequentially, include wrong
-values. After each insertion check whether kni application can be launched
-successfully.
-
-Insert the kernel module 50 times while changing randomly the parameters.
-Iterate through lo_mode and kthread_mode values randomly, include wrong
-values. After each insertion check whether kni application can be launched
-successfully::
-
- rmmod rte_kni
- insmod ./kmod/rte_kni.ko <Changing Parameters>
- ./<build_target>/examples/dpdk-kni -c 0xa0001e -n 4 -- -P -p 0xc --config="(2,1,2,21),(3,3,4,23)"
-
-
-Using ``dmesg`` to check whether kernel module is loaded with the specified
-parameters. Some permutations, those with wrong values, must fail to
-success. For permutations with valid parameter values, verify the application can be
-successfully launched and then close the application using CTRL+C.
