+Kernel NIC Interface
+====================
+
+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 deatil 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
+=============
+
+Support igb_uio and vfio driver, if used vfio, kernel need 3.6+ and enable vt-d in bios.
+When used vfio , used "modprobe vfio" and "modprobe vfio-pci" insmod vfiod driver, then used
+"./tools/dpdk_nic_bind.py --bind=vfio-pci device_bus_id" to bind vfio driver to test driver.
+
+
+The DUT has at least 2 DPDK supported IXGBE 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
+ ./examples/kni/build/app/kni -c 0xa0001e -n 4 -- -P -p 0x3 --config="(0,1,2,21),(1,3,4,23)" &
+
+
+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/app/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
+command ping::
+
+ ping -w 1 -I vEth2_0 192.168.2.1
+
+it can receive all packets and no packet loss::
+
+ PING 192.168.2.1 (192.168.2.1) from 192.168.2.1 vEth2_0: 56(84) bytes of data.
+ 64 bytes from 192.168.2.1: icmp_req=1 ttl=64 time=0.040 ms
+
+ --- 192.168.2.1 ping statistics ---
+ 1 packets transmitted, 1 received, 0% packet loss, time 0ms
+ rtt min/avg/max/mdev = 0.040/0.040/0.040/0.000 ms
+
+Assume ``port A`` on tester is linked with ``port 2`` on DUT. Verify the
+command ping from tester::
+
+ ping -w 1 -I "port A" 192.168.2.1
+
+it can receive all packets and no packet loss.
+
+Verify a wrong address::
+
+ ping -w 1 -I vEth2_0 192.168.0.123
+
+no packets is received::
+
+ PING 192.168.0.123 (192.168.0.123) from 192.168.0.1 vEth2_0: 56(84) bytes of data.
+

+
+Verify the command ping6::
+
+ ping6 -w 1 -I vEth2_0 "Eth2_0's ipv6 address"
+
+it can receive all packets and no packet loss::
+
+ PING fe80::92e2:baff:fe08:d6f0(fe80::92e2:baff:fe08:d6f0) from fe80::92e2:baff:fe08:d6f0 vEth2_0: 56 data bytes
+ 64 bytes from fe80::92e2:baff:fe08:d6f0: icmp_seq=1 ttl=64 time=0.070 ms

+ rtt min/avg/max/mdev = 0.070/0.070/0.070/0.000 ms
+
+Verify the command ping6 from tester::
+
+ ping6 -w 1 -I "port A" "Eth2_0's ipv6 address"
+
+it can receive all packets and no packet loss.
+
+Verify a wrong ipv6 address::
+
+ ping6 -w 1 -I vEth2_0 "random ipv6 address"
+
+no packets is received::
+
+ PING fe80::92e2:baff:fe08:d6f1(fe80::92e2:baff:fe08:d6f1) from fe80::92e2:baff:fe08:d6f0 vEth2_0: 56 data bytes
+
+ --- fe80::92e2:baff:fe08:d6f1 ping statistics ---
+ 1 packets transmitted, 0 received, 100% packet loss, time 0ms
+
+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 belowing commands are to show information commands.
+
+Verify whether ethtool can show Kernel NIC Interface's standard information::
+
+ ethtool vEth2_0
+
+Verify whether ethtool can show Kernel NIC Interface's driver information::
+
+ ethtool -i vEth2_0
+
+Verify whether ethtool can show Kernel NIC Interface's statistics::
+
+ ethtool -S vEth2_0
+
+Verify whether ethtool can show Kernel NIC Interface's pause parameters::
+
+ ethtool -a vEth2_0
+
+Verify whether ethtool can show Kernel NIC Interface's offload parameters::
+
+ ethtool -k vEth2_0
+
+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/app/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/app/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.
+
+Test Case: loopback mode performance testing
+============================================
+
+Compare performance results for loopback mode using:
+
+ - lo_mode: lo_mode_fifo and lo_mode_fifo_skb.
+ - kthread_mode: single and multiple.

+
+ - Different cores for Rx, Tx and Kernel.
+ - Shared core between Rx and Kernel.
+ - Shared cores between Rx and Tx.
+ - Shared cores between Rx, Tx and Kernel.
+ - Multiple cores for Kernel, implies multiple virtual interfaces per port.
