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.
