+ICE PF Enable Buffer Split
+==========================
+
+Description
+===========
+Protocol based buffer split consists of splitting a received packet into two separate regions based on the packet content.
+It is useful in some scenarios, such as GPU acceleration. The splitting will help to enable true zero copy and hence
+improve the performance significantly.
+
+It supports protocol split based on current buffer split. When Rx queue is
+configured with RTE_ETH_RX_OFFLOAD_BUFFER_SPLIT offload and corresponding protocol,
+packets received will be directly split into two different mempools with expected hdr and payload length/content.
+
+For validation, we will focus on:
+1. Configuration of protocol based buffer split is applied.
+Setup buffer split:
+Per port: testpmd>port config 0 rx_offload buffer_split on
+Per queue: testpmd>port 0 rxq 0 rx_offload buffer_split on
+
+Set the protocol type of buffer split:
+testpmd>set rxhdrs eth|ipv4|ipv6|ipv4-tcp|ipv6-tcp|ipv4-udp|ipv6-udp|
+ ipv4-sctp|ipv6-sctp|grenat|inner-eth|inner-ipv4|inner-ipv6|
+ inner-ipv4-tcp|inner-ipv6-tcp|inner-ipv4-udp|inner-ipv6-udp|
+ inner-ipv4-sctp|inner-ipv6-sctp
+
+2. Packets received in ice scalar path(--force-max-simd-bitwidth=64) can be devided into
+ two mempools with expected hdr and payload length/content specified by protocol type.

+.. note::
+
+ 1. Each combination just need to change the IP* with IPV4 or IPV6, the inputset is same. there are 4 combinations in total:
+ IPV4+IPV4
+ IPV4+IPV6
+ IPV6+IPV4
+ IPV6+IPV6
+ 2. UDP tunnel only for VXLAN, for VXLAN case MAC_IPV4_TUN_*** means MAC_IPV4_UDP_VXLAN_***, for GRE case MAC_IPV4_TUN_*** means MAC_IPV4_GRE_***
