+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
---------------------------
kernel driver, which don't want to use the TPID.
So PMD reports warning to clarify what is changed by writing global register.
+Cloud Filter
+~~~~~~~~~~~~
+
+When programming cloud filters for IPv4/6_UDP/TCP/SCTP with SRC port only or DST port only,
+it will make any cloud filter using inner_vlan or tunnel key invalid. Default configuration will be
+recovered only by NIC core reset.
+
High Performance of Small Packets on 40GbE NIC
----------------------------------------------
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.
