+Flow Bifurcation How-to Guide
+=============================
+
+Flow Bifurcation is a mechanism which uses hardware capable Ethernet devices
+to split traffic between Linux user space and kernel space. Since it is a
+hardware assisted feature this approach can provide line rate processing
+capability. Other than :ref:`KNI <kni>`, the software is just required to
+enable device configuration, there is no need to take care of the packet
+movement during the traffic split. This can yield better performance with
+less CPU overhead.
+
+The Flow Bifurcation splits the incoming data traffic to user space
+applications (such as DPDK applications) and/or kernel space programs (such as
+the Linux kernel stack). It can direct some traffic, for example data plane
+traffic, to DPDK, while directing some other traffic, for example control
+plane traffic, to the traditional Linux networking stack.
+
+There are a number of technical options to achieve this. A typical example is
+to combine the technology of SR-IOV and packet classification filtering.
+
+SR-IOV is a PCI standard that allows the same physical adapter to be split as
+multiple virtual functions. Each virtual function (VF) has separated queues
+with physical functions (PF). The network adapter will direct traffic to a
+virtual function with a matching destination MAC address. In a sense, SR-IOV
+has the capability for queue division.
+
+Packet classification filtering is a hardware capability available on most
+network adapters. Filters can be configured to direct specific flows to a
+given receive queue by hardware. Different NICs may have different filter
+types to direct flows to a Virtual Function or a queue that belong to it.
+
+In this way the Linux networking stack can receive specific traffic through
+the kernel driver while a DPDK application can receive specific traffic
+bypassing the Linux kernel by using drivers like VFIO or the DPDK ``igb_uio``
+module.

+
+   Flow Bifurcation Overview
+
+
+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_nic_bind.py -b vfio-pci 01:10.0
+       dpdk_nic_bind.py -b vfio-pci 01:10.1
+
+#. Run a DPDK application on the VFs:
+
+   .. code-block:: console
+
+       testpmd -c 0xff -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_nic_bind.py -b vfio-pci 01:10.0
+       dpdk_nic_bind.py -b vfio-pci 01:10.1
+
+#. run DPDK application on VFs:
+
+   .. code-block:: console
+
+       testpmd -c 0xff -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://dpdk.org/browse/tools/dts/tree/test_plans/cloud_filter_test_plan.rst>`_

+
+Live Migration of VM with SR-IOV VF
+===================================
+
+Overview
+--------
+
+It is not possible to migrate a Virtual Machine which has an SR-IOV Virtual Function (VF).
+
+To get around this problem the bonding PMD is used.
+
+The following sections show an example of how to do this.
+
+Test Setup
+----------
+
+A bonded device is created in the VM.
+The virtio and VF PMD's are added as slaves to the bonded device.
+The VF is set as the primary slave of the bonded device.
+
+A bridge must be set up on the Host connecting the tap device, which is the
+backend of the Virtio device and the Physical Function (PF) device.
+
+To test the Live Migration two servers with identical operating systems installed are used.
+KVM and Qemu 2.3 is also required on the servers.
+
+In this example, the servers have Niantic and or Fortville NIC's installed.
+The NIC's on both servers are connected to a switch
+which is also connected to the traffic generator.
+
+The switch is configured to broadcast traffic on all the NIC ports.
+A :ref:`Sample switch configuration <lm_bond_virtio_sriov_switch_conf>`
+can be found in this section.
+
+The host is running the Kernel PF driver (ixgbe or i40e).
+
+The ip address of host_server_1 is 10.237.212.46
+
+The ip address of host_server_2 is 10.237.212.131
+
+.. _figure_lm_bond_virtio_sriov:
+
+.. figure:: img/lm_bond_virtio_sriov.*
+
+Live Migration steps
+--------------------
+
+The sample scripts mentioned in the steps below can be found in the
+:ref:`Sample host scripts <lm_bond_virtio_sriov_host_scripts>` and
+:ref:`Sample VM scripts <lm_bond_virtio_sriov_vm_scripts>` sections.
+

+   ./connect_to_qemu_mon_on_host.sh
+   (qemu)
+
+On host_server_1: Terminal 1
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**In VM on host_server_1:**
+
+.. code-block:: console
+
+   cd /root/dpdk/vm_scripts
+   ./setup_dpdk_in_vm.sh
+   ./run_testpmd_bonding_in_vm.sh

+
+The ``mac_addr`` command only works with kernel PF for Niantic
+
+.. code-block:: console
+
+   testpmd> mac_addr add port 1 vf 0 AA:BB:CC:DD:EE:FF
+
+The syntax of the ``testpmd`` command is:
+
+Create bonded device (mode) (socket).
+
+Mode 1 is active backup.
+
+Virtio is port 0 (P0).
+
+VF is port 1 (P1).
+
+Bonding is port 2 (P2).
+
+.. code-block:: console
+
+   testpmd> create bonded device 1 0
+   Created new bonded device eth_bond_testpmd_0 on (port 2).
+   testpmd> add bonding slave 0 2
+   testpmd> add bonding slave 1 2
+   testpmd> show bonding config 2
+
+The syntax of the ``testpmd`` command is:
+
+set bonding primary (slave id) (port id)
+
+Set primary to P1 before starting bonding port.
+
+.. code-block:: console
+
+   testpmd> set bonding primary 1 2
+   testpmd> show bonding config 2
+   testpmd> port start 2
+   Port 2: 02:09:C0:68:99:A5

+   Port 0 Link Up - speed 10000 Mbps - full-duplex
+   Port 1 Link Up - speed 10000 Mbps - full-duplex
+   Port 2 Link Up - speed 10000 Mbps - full-duplex
+
+   testpmd> show bonding config 2
+
+Primary is now P1. There are 2 active slaves.
+
+Use P2 only for forwarding.
+
+.. code-block:: console
+
+   testpmd> set portlist 2
+   testpmd> show config fwd
+   testpmd> set fwd mac
+   testpmd> start
+   testpmd> show bonding config 2
+
+Primary is now P1. There are 2 active slaves.
+
+.. code-block:: console
+
+   testpmd> show port stats all
+
+VF traffic is seen at P1 and P2.
+
+.. code-block:: console
+
+   testpmd> clear port stats all
+   testpmd> set bonding primary 0 2
+   testpmd> remove bonding slave 1 2
+   testpmd> show bonding config 2
+
+Primary is now P0. There is 1 active slave.
+
+.. code-block:: console
+
+   testpmd> clear port stats all
+   testpmd> show port stats all
+
+No VF traffic is seen at P0 and P2, VF MAC address still present.
+
+.. code-block:: console
+
+   testpmd> port stop 1
+   testpmd> port close 1
+
+Port close should remove VF MAC address, it does not remove perm_addr.
+
+The ``mac_addr`` command only works with the kernel PF for Niantic.
+
+.. code-block:: console
+
+   testpmd> mac_addr remove 1 AA:BB:CC:DD:EE:FF
+   testpmd> port detach 1
+   Port '0000:00:04.0' is detached. Now total ports is 2
+   testpmd> show port stats all
+
+No VF traffic is seen at P0 and P2.

+---------------------------
+
+The Intel switch is used to connect the traffic generator to the
+NIC's on host_server_1 and host_server_2.
+
+In order to run the switch configuration two console windows are required.
+
+Log in as root in both windows.
+
+TestPointShared, run_switch.sh and load /root/switch_config must be executed
+in the sequence below.
+
+On Switch: Terminal 1

+Live Migration of VM with Virtio on host running vhost_user
+===========================================================
+
+Overview
+--------
+
+Live Migration of a VM with DPDK Virtio PMD on a host which is
+running the Vhost sample application (vhost-switch) and using the DPDK PMD (ixgbe or i40e).
+
+The Vhost sample application uses VMDQ so SRIOV must be disabled on the NIC's.
+
+The following sections show an example of how to do this migration.
+
+Test Setup
+----------
+
+To test the Live Migration two servers with identical operating systems installed are used.
+KVM and QEMU is also required on the servers.
+
+QEMU 2.5 is required for Live Migration of a VM with vhost_user running on the hosts.
+
+In this example, the servers have Niantic and or Fortville NIC's installed.
+The NIC's on both servers are connected to a switch
+which is also connected to the traffic generator.
+
+The switch is configured to broadcast traffic on all the NIC ports.
+
+The ip address of host_server_1 is 10.237.212.46
+
+The ip address of host_server_2 is 10.237.212.131
