doc: remove Intel PMD examples in flow bifurcation guide
Now this feature is no longer supported by kernel side, (i40e kernel driver doesn't support it from v2.3.2 and ixgbe kernel driver isn't guaranteed to support this feature as well in the future), so remove the Intel PMD examples to avoid confusion.

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
|
||||
|

|
||||
|
||||
* Inner mac, for a route whose inner destination mac is 0:0:0:0:9:0 to
|
||||
PF's queue 6.
|
||||
|

|
||||
|
||||
* 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 \

|
||||

|
||||
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.

|

|
||||
|

* 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 \

|
||||
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.
|

#. run DPDK application on VFs:

.. code-block:: console
|

|
||||
* 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'.
