Prerequisites
-------------
- Upgrade the NVM/FW version following the `Intel® Ethernet NVM Update Tool Quick Usage Guide for Linux
<https://www-ssl.intel.com/content/www/us/en/embedded/products/networking/nvm-update-tool-quick-linux-usage-guide.html>`_ and `Intel® Ethernet NVM Update Tool: Quick Usage Guide for EFI <https://www.intel.com/content/www/us/en/embedded/products/networking/nvm-update-tool-quick-efi-usage-guide.html>`_ if needed.
+- For information about supported media, please refer to this document: `Intel® Ethernet Controller X710/XXV710/XL710 Feature Support Matrix

+ .. Note::
+
+ * Some adapters based on the Intel(R) Ethernet Controller 700 Series only
+ support Intel Ethernet Optics modules. On these adapters, other modules are not
+ supported and will not function.
+
+ * For connections based on Intel(R) Ethernet Controller 700 Series,
+ support is dependent on your system board. Please see your vendor for details.
+
+ * In all cases Intel recommends using Intel Ethernet Optics; other modules
+ may function but are not validated by Intel. Contact Intel for supported media types.

+Generic flow API
+~~~~~~~~~~~~~~~~~~~
+
+- ``RSS Flow``
+
+ RSS Flow supports to set hash input set, hash function, enable hash
+ and configure queue region.
+ For example:
+ Configure queue region as queue 0, 1, 2, 3.
+
+ .. code-block:: console
+
+ testpmd> flow create 0 ingress pattern end actions rss types end \
+ queues 0 1 2 3 end / end
+
+ Enable hash and set input set for ipv4-tcp.
+
+ .. code-block:: console
+
+ testpmd> flow create 0 ingress pattern eth / ipv4 / tcp / end \
+ actions rss types ipv4-tcp l3-src-only end queues end / end
+
+ Set symmetric hash enable for flow type ipv4-tcp.
+
+ .. code-block:: console
+
+ testpmd> flow create 0 ingress pattern eth / ipv4 / tcp / end \
+ actions rss types ipv4-tcp end queues end func symmetric_toeplitz / end
+
+ Set hash function as simple xor.
+
+ .. code-block:: console
+
+ testpmd> flow create 0 ingress pattern end actions rss types end \
+ queues end func simple_xor / end
+
Limitations or Known issues
---------------------------
As i40e PMD supports both 16 and 32 bytes RX descriptor sizes, and 16 bytes size can provide helps to high performance of small packets.
Configuration of ``CONFIG_RTE_LIBRTE_I40E_16BYTE_RX_DESC`` in config files can be changed to use 16 bytes size RX descriptors.
+Input set requirement of each pctype for FDIR
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Each PCTYPE can only have one specific FDIR input set at one time.
+For example, if creating 2 rte_flow rules with different input set for one PCTYPE,
+it will fail and return the info "Conflict with the first rule's input set",
+which means the current rule's input set conflicts with the first rule's.
+Remove the first rule if want to change the input set of the PCTYPE.
