-Niantic Flow Director Tests
-===========================
-
-
-Description
-===========
-
-This document provides the plan for testing the Flow Director (FDir) feature of
-the Intel 82599 10GbE Ethernet Controller. FDir allows an application to add
-filters that identify specific flows (or sets of flows), by examining the VLAN
-header, IP addresses, port numbers, protocol type (IPv4/IPv6, UDP/TCP, SCTP), or
-a two-byte tuple within the first 64 bytes of the packet.
-
-There are two types of filters:
-
-1. Perfect match filters, where there must be a match between the fields of
-   received packets and the programmed filters.
-2. Signature filters, where there must be a match between a hash-based signature
-   if the fields in the received packet.
-
-There is also support for global masks that affect all filters by masking out
-some fields, or parts of fields from the matching process.
-
-Within DPDK, the FDir feature can be configured through the API in the
-lib_ethdev library, and this API is used by the ``testpmd`` application.
-
-Note that RSS features can not be enabled at the same time as FDir.
-
-
-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 a dual port Intel 82599 10GbE Ethernet Controller, with one of these
-ports connected to a port on another device that is controlled by the Scapy
-packet generator.
-
-The Ethernet interface identifier of the port that Scapy will use must be known.
-In all tests below, it is referred to as "eth9".
-
-The following packets should be created in Scapy. Any reasonable MAC address can
-be given but other fields must be as shown::
-

-
-The test commands below assume that port 0 on the DUT is the port that is
-connected to the traffic generator. All fdir cmdline please see doc on http://www.dpdk.org/doc/guides/testpmd_app_ug/testpmd_funcs.html#filter-functions.  If this is not the case, the following
-``testpmd`` commands must be changed, and also the ``--portmask`` parameter.
-
-* ``show port fdir <port>``
-* ``add_perfect_filter <port>``
-* ``add_signature_filter <port>``
-* ``set_masks_filter <port>``
-* ``rx_vlan add all <port>``
-
-Most of the tests below involve sending single packets from the generator and
-checking if the packets match the configured filter, and go to a set queue. To
-see this, there must be multiple queues, setup by passing the following command-
-line arguments: ``--nb-cores=2 --rxq=2 --txq=2``. And at run-time, the
-forwarding mode must be set to rxonly, and the verbosity level > 0::
-
-   testpmd> set verbose 1
-   testpmd> set fwd rxonly
-
-
-Test case: Setting memory reserved for FDir filters
-===================================================
-
-Each FDir filter requires space in the Rx Packet Buffer (perfect filters require
-32 B of space, and signature filters require 8 B of space). The total amount of
-memory - and therefore the number of concurrent filters - can be set when
-initializing FDir.

-Test case: FDir signature matching mode
-=======================================
-
-This test adds signature filters to the hardware, and then checks whether sent
-packets match those filters. In order to this, the packet should first be sent
-from ``Scapy`` before the filter is created, to verify that it is not matched by
-a FDir filter. The filter is then added from the ``testpmd`` command line and
-the packet is sent again.
-
-Launch the userland ``testpmd`` application as follows::
-
-   ./testpmd -c 0xf -- -i --portmask=1 --nb-cores=2 --rxq=2 --txq=2 --disable-rss
-      --pkt-filter-mode=signature
-   testpmd> set verbose 1
-   testpmd> set fwd rxonly
-   testpmd> start
-
-Send the ``p_udp`` packet and verify that there is not a match. Then add the
-filter and check that there is a match::
-
-   testpmd> add_signature_filter 0 udp src 192.168.0.1 1024 dst 192.168.0.2

-Test case: FDir perfect matching mode
-=====================================
-
-This test adds perfect-match filters to the hardware, and then checks whether
-sent packets match those filters. In order to this, the packet should first be
-sent from ``Scapy`` before the filter is created, to verify that it is not
-matched by a FDir filter. The filter is then added from the ``testpmd`` command
-line and the packet is sent again.::
-
-   ./testpmd -c 0xf -- -i --portmask=1 --nb-cores=2 --rxq=2 --txq=2 --disable-rss
-      --pkt-filter-mode=perfect
-   testpmd> set verbose 1
-   testpmd> set fwd rxonly
-   testpmd> start
-
-Send the ``p_udp`` packet and verify that there is not a match. Then add the
-filter and check that there is a match::
-
-   testpmd> add_perfect_filter 0 udp src 192.168.0.1 1024 dst 192.168.0.2 1024

-
-Update the perfect filter match the ``p_udp1`` packet and send the packet and check
-that there is a match::

-Remove the perfect filter match the ``p_udp1`` and ``p_udp`` packets, and send the packet again.
-Check that no FDir information is printed::

-
-Test case: FDir filter masks
-============================
-
-This section tests the functionality of the setting FDir masks to affect
-which fields, or parts of fields are used in the matching process. Note that
-setting up a mask resets all the FDir filters, so the ``testpmd`` application
-does not have to be relaunched for each sub-case.
-
-Launch the userland ``testpmd`` application::
-
-   ./testpmd -c 0xf -- -i --portmask=1 --nb-cores=2 --rxq=2 --txq=2 --disable-rss
-      --pkt-filter-mode=perfect
-   testpmd> set verbose 1
-   testpmd> set fwd rxonly
-   testpmd> start
-
-Sub-case: IP address masking
-----------------------------
-
-Create the following IPv4 mask on port 0. This mask means the lower byte of the
-source and destination IP addresses will not be considered in the matching
-process::
-
-   testpmd> set_masks_filter 0 only_ip_flow 0 src_mask 0xffffff00 0xffff
-      dst_mask 0xffffff00 0xffff flexbytes 1 vlan_id 1 vlan_prio 1
-
-Then, add the following perfect IPv4 filter::
-
-   testpmd> add_perfect_filter 0 udp src 192.168.0.0 1024 dst 192.168.0.0 1024
-      flexbytes 0x800 vlan 0 queue 1 soft 0x17
-
-Then send the ``p_udp_1``, ``p_udp_2``, and ``p_udp_3`` packets from Scapy. The
-first two packets should match the masked filter, but the third packet will not,
-as it differs in the second lowest IP address byte.::
-
-   testpmd> port 0/queue 1: received 1 packets
-      src=00:1B:21:53:1F:14 - dst=00:1B:21:91:3D:2C - type=0x0800 - length=60 - nb_segs=1
-      - FDIR hash=0x6cf - FDIR id=0x17
-      PKT_RX_PKT_RX_FDIR
-      PKT_RX_IP_CKSUM
-      PKT_RX_IPV4_HDR
-   port 0/queue 1: received 1 packets
-      src=00:1B:21:53:1F:14 - dst=00:1B:21:91:3D:2C - type=0x0800 - length=60 - nb_segs=1
-      - FDIR hash=0x6cf - FDIR id=0x17
-      PKT_RX_PKT_RX_FDIR
-      PKT_RX_IP_CKSUM
-      PKT_RX_IPV4_HDR
-   port 0/queue 0: received 1 packets
-      src=00:1B:21:53:1F:14 - dst=00:1B:21:91:3D:2C - type=0x0800 - length=60 - nb_segs=1
-      PKT_RX_IP_CKSUM
-      PKT_RX_IPV4_HDR
-
-
-Sub-case: Port masking
-----------------------
-
-Create the following mask on port 0. This mask means the lower byte of the
-source and destination ports will not be considered in the matching process::
-
-   testpmd> set_masks_filter 0 only_ip_flow 0 src_mask 0xffffffff 0xff00
-      dst_mask 0xffffffff 0xff00 flexbytes 1 vlan_id 1 vlan_prio 1
-
-Then, add the following perfect IPv4 filter::
-
-   testpmd> add_perfect_filter 0 udp src 10.11.12.1 0x4400 dst 10.11.12.2 0x4500
-      flexbytes 0x800 vlan 0 queue 1 soft 0x4
-
-Then send the ``p_udp_4``, ``p_udp_5``, and ``p_udp_6`` packets from Scapy. The
-first two packets should match the masked filter, but the third packet will not,
-as it differs in higher byte of the port numbers.::
-
-   testpmd> port 0/queue 1: received 1 packets
-      src=00:1B:21:53:1F:14 - dst=00:1B:21:91:3D:2C - type=0x0800 - length=60 - nb_segs=1
-      - FDIR hash=0x41d - FDIR id=0x4
-      PKT_RX_PKT_RX_FDIR
-      PKT_RX_IP_CKSUM

-Sub-case: L4Type field masking
-------------------------------
-
-Create the following mask on port 0. This mask means that the L4type field of
-packets will not be considered. Note that in this case, the source and the
-destination port masks are irrelevant and must be set to zero::
-
-   testpmd> set_masks_filter 0 only_ip_flow 1 src_mask 0xffffffff 0x0
-      dst_mask 0xffffffff 0x0 flexbytes 1 vlan_id 1 vlan_prio 1
-
-Then, add the following perfect IPv4 filter::
-
-   testpmd> add_perfect_filter 0 ip src 192.168.0.1 0 dst 192.168.0.2 0
-      flexbytes 0x800 vlan 0 queue 1 soft 0x42
-
-Then send the ``p_udp`` and ``p_tcp`` packets from Scapy. Both packets will
-match the filter::
-
-   testpmd> port 0/queue 1: received 1 packets
-      src=00:1B:21:53:1F:14 - dst=00:1B:21:91:3D:2C - type=0x0800 - length=60 - nb_segs=1

-Test case: FDir ``flexbytes`` filtering
-=======================================
-
-The FDir feature supports setting up filters that can match on any two byte
-field within the first 64 bytes of a packet. Which byte offset to use is
-set by passing command line arguments to ``testpmd``. In this test a value of
-``18`` corresponds to the bytes at offset 36 and 37, as the offset is in 2-byte
-units::
-
-   ./testpmd -c 0xf -- -i --portmask=1 --nb-cores=2 --rxq=2 --txq=2 --disable-rss
-      --pkt-filter-mode=perfect --pkt-filter-flexbytes-offset=18
-   testpmd> set verbose 1
-   testpmd> set fwd rxonly
-   testpmd> start
-
-Send the ``p_gre1`` packet and verify that there is not a match. Then add the
-filter and check that there is a match::
-
-   testpmd> add_perfect_filter 0 ip src 192.168.0.1 0 dst 192.168.0.2 0 flexbytes 0x1 vlan 0 queue 1 soft 0x1
-   testpmd> port 0/queue 1: received 1 packets
-      src=00:1B:21:53:1F:14 - dst=00:1B:21:91:3D:2C - type=0x0800 - length=66 - nb_segs=1
-      - FDIR hash=0x18b - FDIR id=0x1
-      PKT_RX_PKT_RX_FDIR
-      PKT_RX_IP_CKSUM
-      PKT_RX_IPV4_HDR
-
-Send the ``p_gre2`` packet and verify that there is not a match. Then add a
-second filter and check that there is a match::
-
-   testpmd> add_perfect_filter 0 ip src 192.168.0.1 0 dst 192.168.0.2 0 flexbytes 0xff vlan 0 queue 1 soft 0xff
-   testpmd> port 0/queue 1: received 1 packets
-      src=00:1B:21:53:1F:14 - dst=00:1B:21:91:3D:2C - type=0x0800 - length=66 - nb_segs=1 - FDIR hash=0x3a1 - FDIR id=0xff
-      PKT_RX_PKT_RX_FDIR
-      PKT_RX_IP_CKSUM
-      PKT_RX_IPV4_HDR
-
-
-Sub-case: ``flexbytes`` FDir masking
-------------------------------------
-
-A mask can also be applied to the ``flexbytes`` filter::
-
-   testpmd> set_masks_filter 0 only_ip_flow 0 src_mask 0xffffffff 0xffff
-      dst_mask 0xffffffff 0xffff flexbytes 0 vlan_id 1 vlan_prio 1
-
-Then, add the following perfect filter (same as first filter in prev. test), and
-check that this time both packets match (``p_gre1`` and ``p_gre2``)::
-
-   testpmd> add_perfect_filter 0 ip src 192.168.0.1 0 dst 192.168.0.2 0 flexbytes 0x0 vlan 0 queue 1 soft 0x42
-   testpmd> port 0/queue 1: received 1 packets
-      src=00:1B:21:53:1F:14 - dst=00:1B:21:91:3D:2C - type=0x0800 - length=66 - nb_segs=1 - FDIR hash=0x2f3 - FDIR id=0x42

-      PKT_RX_IPV4_HDR
-   port 0/queue 1: received 1 packets
-      src=00:1B:21:53:1F:14 - dst=00:1B:21:91:3D:2C - type=0x0800 - length=66 - nb_segs=1 - FDIR hash=0x2f3 - FDIR id=0x42

-      PKT_RX_IP_CKSUM
-      PKT_RX_IPV4_HDR
-
-
-Test case: FDir VLAN field filtering
-====================================
-
-Connect port 0 of the DUT to a traffic generator capable of sending packets with
-VLAN headers.
-
-Then launch the ``testpmd`` application, and enable VLAN packet reception::
-
-   ./testpmd -c 0xf -- -i --portmask=1 --nb-cores=2 --rxq=2 --txq=2 --disable-rss --pkt-filter-mode=perfect
-   testpmd> set verbose 1
-   testpmd> set fwd rxonly
-   testpmd> rx_vlan add all 0
-   testpmd> start
-
-From the traffic generator, transmit a packet with the following details, and
-verify that it does not match any FDir filters.:
-
-* VLAN ID = 0x0FFF
-* IP source address = 192.168.0.1
-* IP destination address = 192.168.0.2
-* UDP source port = 1024
-* UDP destination port = 1024
-
-Then, add the following perfect VLAN filter, resend the packet and verify that
-it matches the filter::
-
-   testpmd> add_perfect_filter 0 udp src 192.168.0.1 1024 dst 192.168.0.2 1024
-      flexbytes 0x8100 vlan 0xfff queue 1 soft 0x47
-   testpmd> port 0/queue 1: received 1 packets
-      src=00:00:03:00:03:00 - dst=00:00:03:00:02:00 - type=0x0800 - length=64 - nb_segs=1
-      - FDIR hash=0x7e9 - FDIR id=0x47   - VLAN tci=0xfff

-      PKT_RX_PKT_RX_FDIR
-      PKT_RX_IP_CKSUM
-      PKT_RX_IPV4_HDR
-
-
-Sub-case: VLAN field masking
-----------------------------
-
-First, set the following mask to disable the matching of the VLAN field, and add
-a perfect filter to match any VLAN identifier::
-
-   testpmd> set_masks_filter 0 only_ip_flow 0 src_mask 0xffffffff 0xffff
-      dst_mask 0xffffffff 0xffff flexbytes 1 vlan_id 0 vlan_prio 0
-   testpmd> add_perfect_filter 0 udp src 192.168.0.1 1024 dst 192.168.0.2 1024
-      flexbytes 0x8100 vlan 0 queue 1 soft 0x47
-
-Then send the same packet above, but with the VLAN field change first to 0x001,
-and then to 0x0017. The packets should still match the filter:::
-
-   testpmd> port 0/queue 1: received 1 packets
-   src=00:00:03:00:03:00 - dst=00:00:03:00:02:00 - type=0x0800 - length=64 - nb_segs=1
-      - FDIR hash=0x7e8 - FDIR id=0x47   - VLAN tci=0x1
-   PKT_RX_VLAN_PKT
-   PKT_RX_PKT_RX_FDIR
-   PKT_RX_IP_CKSUM
-   PKT_RX_IPV4_HDR
-   port 0/queue 1: received 1 packets
-   src=00:00:03:00:03:00 - dst=00:00:03:00:02:00 - type=0x0800 - length=64 - nb_segs=1

-Test Case 3: test with ivlan   (qinq not work)
-==============================================
-
-1. start testpmd and initialize flow director flex payload configuration::
-
-      ./testpmd -c fffff -n 4 -- -i --disable-rss --pkt-filter-mode=perfect --rxq=8 --txq=8 --nb-cores=8
-      testpmd> port stop 0
-      testpmd> flow_director_flex_payload 0 l2 (0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15)
-      testpmd> flow_director_flex_payload 0 l3 (0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15)
-      testpmd> flow_director_flex_payload 0 l4 (0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15)
-      testpmd> flow_director_flex_mask 0 flow all (0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff)
-      testpmd> port start 0
-
-      testpmd> vlan set qinq on 0
-
-      testpmd> set verbose 1
-      testpmd> set fwd rxonly
-      testpmd> start
-
-   Note::
-
-      assume FLEXBYTES = "0x11,0x11,0x22,0x22,0x33,0x33,0x44,0x44,0x55,0x55,0x66,0x66,0x77,0x77,0x88,0x88"

-
-2. setup the fdir input set::
-
-      testpmd> set_fdir_input_set 0 ipv4-udp none select
-      testpmd> set_fdir_input_set 0 ipv4-udp ivlan add
-
-
-3. setup flow director filter rules,
-
-   rule_1::
-
-      flow_director_filter 0 mode IP add flow ipv4-udp src 192.168.1.1 1021 dst 192.168.1.2 1022 tos 16 ttl 255 \

-      vlan 15 flexbytes (FLEXBYTES) fwd pf queue 2 fd_id 2
-
-   rule_3::
-

-      tos=16, ttl=255)/UDP(sport="1021",dport="1022")/Raw(%s)], iface="%s")' % (dst_mac, payload, itf)
-
-   packet_3 should be received by queue 3.
-

-      tos=16, ttl=255)/UDP(sport="1021",dport="1022")/Raw(%s)], iface="%s")' % (dst_mac, payload, itf)
-
-   packet_4 should be received by queue 4.
-
-   * Delete rule_1, send packet_1 again, packet_1 should be received by queue 0.
-   * Delete rule_2, send packet_2 again, packet_2 should be received by queue 0.
-   * Delete rule_3, send packet_3 again, packet_3 should be received by queue 0.
-   * Delete rule_4, send packet_4 again, packet_4 should be received by queue 0.
-
-5. removed all entry of fdir::
-
-      testpmd>flush_flow_director 0
-      testpmd>show port fdir 0
