-Using Flow Bifurcation on IXGBE in Linux
-----------------------------------------
-
-On Intel 82599 10 Gigabit Ethernet Controller series NICs Flow Bifurcation can
-be achieved by SR-IOV and Intel Flow Director technologies. Traffic can be
-directed to queues by the Flow Director capability, typically by matching
-5-tuple of UDP/TCP packets.
-
-The typical procedure to achieve this is as follows:
-
-#. Boot the system without iommu, or with ``iommu=pt``.
-
-#. Create Virtual Functions:
-
-   .. code-block:: console
-
-       echo 2 > /sys/bus/pci/devices/0000:01:00.0/sriov_numvfs
-
-#. Enable and set flow filters:
-
-   .. code-block:: console
-
-       ethtool -K eth1 ntuple on
-       ethtool -N eth1 flow-type udp4 src-ip 192.0.2.2 dst-ip 198.51.100.2 \
-               action $queue_index_in_VF0
-       ethtool -N eth1 flow-type udp4 src-ip 198.51.100.2 dst-ip 192.0.2.2 \
-               action $queue_index_in_VF1
-
-   Where:
-
-   * ``$queue_index_in_VFn``: Bits 39:32 of the variable defines VF id + 1; the lower 32 bits indicates the queue index of the VF. Thus:
-
-     * ``$queue_index_in_VF0`` = ``(0x1 & 0xFF) << 32 + [queue index]``.
-
-     * ``$queue_index_in_VF1`` = ``(0x2 & 0xFF) << 32 + [queue index]``.
-
-   .. _figure_ixgbe_bifu_queue_idx:
-
-   .. figure:: img/ixgbe_bifu_queue_idx.*
-
-#. Compile the DPDK application and insert ``igb_uio`` or probe the ``vfio-pci`` kernel modules as normal.
-
-#. Bind the virtual functions:
-
-   .. code-block:: console
-
-       modprobe vfio-pci
-       dpdk-devbind.py -b vfio-pci 01:10.0
-       dpdk-devbind.py -b vfio-pci 01:10.1
-
-#. Run a DPDK application on the VFs:
-
-   .. code-block:: console
-
-       testpmd -l 0-7 -n 4 -- -i -w 01:10.0 -w 01:10.1 --forward-mode=mac
-
-In this example, traffic matching the rules will go through the VF by matching
-the filter rule. All other traffic, not matching the rules, will go through
-the default queue or scaling on queues in the PF. That is to say UDP packets
-with the specified IP source and destination addresses will go through the
-DPDK application. All other traffic, with different hosts or different
-protocols, will go through the Linux networking stack.
-
-.. note::
-
-    * The above steps work on the Linux kernel v4.2.
-
-    * The Flow Bifurcation is implemented in Linux kernel and ixgbe kernel driver using the following patches:
-
-        * `ethtool: Add helper routines to pass vf to rx_flow_spec <https://patchwork.ozlabs.org/patch/476511/>`_
-
-        * `ixgbe: Allow flow director to use entire queue space <https://patchwork.ozlabs.org/patch/476516/>`_
-
-    * The Ethtool version used in this example is 3.18.
-
-
-Using Flow Bifurcation on I40E in Linux
----------------------------------------
-
-On Intel X710/XL710 series Ethernet Controllers Flow Bifurcation can be
-achieved by SR-IOV, Cloud Filter and L3 VEB switch. The traffic can be
-directed to queues by the Cloud Filter and L3 VEB switch's matching rule.
-
-* L3 VEB filters work for non-tunneled packets. It can direct a packet just by
-  the Destination IP address to a queue in a VF.
-
-* Cloud filters work for the following types of tunneled packets.
-
-    * Inner mac.
-
-    * Inner mac + VNI.
-
-    * Outer mac + Inner mac + VNI.
-
-    * Inner mac + Inner vlan + VNI.
-
-    * Inner mac + Inner vlan.
-
-The typical procedure to achieve this is as follows:
-
-#. Boot the system without iommu, or with ``iommu=pt``.
-
-#. Build and insert the ``i40e.ko`` module.
-
-#. Create Virtual Functions:
-
-   .. code-block:: console
-
-       echo 2 > /sys/bus/pci/devices/0000:01:00.0/sriov_numvfs
-
-#. Add udp port offload to the NIC if using cloud filter:
-
-   .. code-block:: console
-
-       ip li add vxlan0 type vxlan id 42 group 239.1.1.1 local 10.16.43.214 dev <name>
-       ifconfig vxlan0 up
-       ip -d li show vxlan0
-
-   .. note::
-
-       Output such as ``add vxlan port 8472, index 0 success`` should be
-       found in the system log.
-
-#. Examples of enabling and setting flow filters:
-
-   * L3 VEB filter, for a route whose destination IP is 192.168.50.108 to VF
-     0's queue 2.
-
-     .. code-block:: console
-
-       ethtool -N <dev_name> flow-type ip4 dst-ip 192.168.50.108 \
-               user-def 0xffffffff00000000 action 2 loc 8
-
-   * Inner mac, for a route whose inner destination mac is 0:0:0:0:9:0 to
-     PF's queue 6.
-
-     .. code-block:: console
-
-       ethtool -N <dev_name> flow-type ether dst 00:00:00:00:00:00 \
-               m ff:ff:ff:ff:ff:ff src 00:00:00:00:09:00 m 00:00:00:00:00:00 \
-               user-def 0xffffffff00000003 action 6 loc 1
-
-   * Inner mac + VNI, for a route whose inner destination mac is 0:0:0:0:9:0
-     and VNI is 8 to PF's queue 4.
-
-     .. code-block:: console
-
-       ethtool -N <dev_name> flow-type ether dst 00:00:00:00:00:00 \
-               m ff:ff:ff:ff:ff:ff src 00:00:00:00:09:00 m 00:00:00:00:00:00 \
-               user-def 0x800000003 action 4 loc 4
-
-   * Outer mac + Inner mac + VNI, for a route whose outer mac is
-     68:05:ca:24:03:8b, inner destination mac is c2:1a:e1:53:bc:57, and VNI
-     is 8 to PF's queue 2.
-
-     .. code-block:: console
-
-       ethtool -N <dev_name> flow-type ether dst 68:05:ca:24:03:8b \
-               m 00:00:00:00:00:00 src c2:1a:e1:53:bc:57 m 00:00:00:00:00:00 \
-               user-def 0x800000003 action 2 loc 2
-
-   * Inner mac + Inner vlan + VNI, for a route whose inner destination mac is
-     00:00:00:00:20:00, inner vlan is 10, and VNI is 8 to VF 0's queue 1.
-
-     .. code-block:: console
-
-       ethtool -N <dev_name> flow-type ether dst 00:00:00:00:01:00 \
-               m ff:ff:ff:ff:ff:ff src 00:00:00:00:20:00 m 00:00:00:00:00:00 \
-               vlan 10 user-def 0x800000000 action 1 loc 5
-
-   * Inner mac + Inner vlan, for a route whose inner destination mac is
-     00:00:00:00:20:00, and inner vlan is 10 to VF 0's queue 1.
-
-     .. code-block:: console
-
-       ethtool -N <dev_name> flow-type ether dst 00:00:00:00:01:00 \
-               m ff:ff:ff:ff:ff:ff src 00:00:00:00:20:00 m 00:00:00:00:00:00 \
-               vlan 10 user-def 0xffffffff00000000 action 1 loc 5
-
-   .. note::
-
-       * If the upper 32 bits of 'user-def' are ``0xffffffff``, then the
-         filter can be used for programming an L3 VEB filter, otherwise the
-         upper 32 bits of 'user-def' can carry the tenant ID/VNI if
-         specified/required.
-
-       * Cloud filters can be defined with inner mac, outer mac, inner ip,
-         inner vlan and VNI as part of the cloud tuple. It is always the
-         destination (not source) mac/ip that these filters use. For all
-         these examples dst and src mac address fields are overloaded dst ==
-         outer, src == inner.
-
-       * The filter will direct a packet matching the rule to a vf id
-         specified in the lower 32 bit of user-def to the queue specified by
-         'action'.
-
-       * If the vf id specified by the lower 32 bit of user-def is greater
-         than or equal to ``max_vfs``, then the filter is for the PF queues.
-
-#. Compile the DPDK application and insert ``igb_uio`` or probe the ``vfio-pci``
-   kernel modules as normal.
-
-#. Bind the virtual function:
-
-   .. code-block:: console
-
-       modprobe vfio-pci
-       dpdk-devbind.py -b vfio-pci 01:10.0
-       dpdk-devbind.py -b vfio-pci 01:10.1
-
-#. run DPDK application on VFs:
-
-   .. code-block:: console
-
-       testpmd -l 0-7 -n 4 -- -i -w 01:10.0 -w 01:10.1 --forward-mode=mac
-
-.. note::
-
-   * The above steps work on the i40e Linux kernel driver v1.5.16.
-
-   * The Ethtool version used in this example is 3.18. The mask ``ff`` means
-     'not involved', while ``00`` or no mask means 'involved'.
-
-   * For more details of the configuration, refer to the
-     `cloud filter test plan <http://git.dpdk.org/tools/dts/tree/test_plans/cloud_filter_test_plan.rst>`_
