The splitting will help to enable true zero copy and hence \n+improve the performance significantly.\n+\n+It supports protocol split based on current buffer split. When Rx queue is \n+configured with RTE_ETH_RX_OFFLOAD_BUFFER_SPLIT offload and corresponding protocol, \n+packets received will be directly split into two different mempools with expected hdr and payload length/content.\n+\n+For validation, we will focus on:\n+1. Configuration of protocol based buffer split is applied.\n+Setup buffer split:\n+Per port: testpmd>port config 0 rx_offload buffer_split on\n+Per queue: testpmd>port 0 rxq 0 rx_offload buffer_split on\n+\n+Set the protocol type of buffer split:\n+testpmd>set rxhdrs (eth|ipv4|ipv6|ipv4-tcp|ipv6-tcp|ipv4-udp|ipv6-udp|\n+ipv4-sctp|ipv6-sctp|grenat|inner-eth|inner-ipv4|inner-ipv6|\n+inner-ipv4-tcp|inner-ipv6-tcp|inner-ipv4-udp|inner-ipv6-udp|\n+inner-ipv4-sctp|inner-ipv6-sctp)\n+\n+2. Packets received in ice scalar path(--force-max-simd-bitwidth=64) can be devided into \n+two mempools with expected hdr and payload length/content specified by protocol type.\n+\n+.. note::\n+\n+    Currently, it supports 6 kinds segmentation of buffer split.\n+    * Outer mac: set rxhdrs eth\n+    * Inner mac: set rxhdrs inner-eth\n+    * Inner l3: set rxhdrs ipv4|ipv6|inner-ipv4|inner-ipv6\n+    * Inner l4: set rxhdrs ipv4-udp|ipv4-tcp|ipv6-udp|ipv6-tcp|inner-ipv4-udp|inner-ipv4-tcp|inner-ipv6-udp|inner-ipv6-tcp\n+    * Inner sctp: set rxhdrs ipv4-sctp|ipv6-sctp|inner-ipv4-sctp|inner-ipv6-sctp\n+    * Tunnel: set rxhdrs grenat\n+\n+Prerequisites\n+=============\n+\n+Topology\n+--------\n+DUT port 0 <----> Tester port 0\n+\n+Hardware\n+--------\n+Supported NICs: Intel® Ethernet 800 Series E810-XXVDA4/E810-CQ\n+\n+Software\n+--------\n+dpdk: http://dpdk.org/git/dpdk\n+runtime command: https://doc.dpdk.org/guides/testpmd_app_ug/testpmd_funcs.html\n+\n+General Set Up\n+--------------\n+1.
