+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::
+
+    Currently, it supports 6 kinds segmentation of buffer split:
+    * Outer mac: set rxhdrs eth
+    * Inner mac: set rxhdrs inner-eth
+    * Inner l3: set rxhdrs ipv4|ipv6|inner-ipv4|inner-ipv6
+    * Inner l4: set rxhdrs ipv4-udp|ipv4-tcp|ipv6-udp|ipv6-tcp|inner-ipv4-udp|inner-ipv4-tcp|inner-ipv6-udp|inner-ipv6-tcp
+    * Inner sctp: set rxhdrs ipv4-sctp|ipv6-sctp|inner-ipv4-sctp|inner-ipv6-sctp
+    * Tunnel: set rxhdrs grenat
+
+Prerequisites
+=============
+
+Topology
+--------
+DUT port 0 <----> Tester port 0
+
+Hardware
+--------
+Supported NICs: Intel® Ethernet 800 Series E810-XXVDA4/E810-CQ
+
+Software
+--------
+dpdk: http://dpdk.org/git/dpdk
+runtime command: https://doc.dpdk.org/guides/testpmd_app_ug/testpmd_funcs.html
+
+General Set Up
+--------------
+1. Compile DPDK with '-Dc_args='-DRTE_ETHDEV_DEBUG_RX=1' to dump segment data::
+
+    # CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dc_args='-DRTE_ETHDEV_DEBUG_RX=1' --default-library=static <dpdk build dir>
+    # ninja -C <dpdk build dir> -j 110
+
+2. Get the pci device id and interface of DUT and tester.
+   For example, 0000:3b:00.0 and 0000:3b:00.1 is pci device id,
+   ens785f0 and ens785f1 is interface::
+
+    <dpdk dir># ./usertools/dpdk-devbind.py -s
+
+    0000:3b:00.0 'Device 159b' if=ens785f0 drv=ice unused=vfio-pci
+    0000:3b:00.1 'Device 159b' if=ens785f1 drv=ice unused=vfio-pci
+
+3. Bind the DUT port to dpdk::
+
+    <dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port pci device id> 
+
+Test Case
+=========
+The test case verifies the buffer split of 6 packets:
+* MAC_IPV4_UDP_PAY
