This v2 is a lot better for the users to understand what happens. Fixed the indent and moved few words: * ethdev: Since no single PMD supports ``RTE_ETH_RX_OFFLOAD_HEADER_SPLIT`` offload and the ``split_hdr_size`` field in structure ``rte_eth_rxmode`` to enable per-port header split, they will be removed in DPDK 22.11. The per-queue Rx packet split offload ``RTE_ETH_RX_OFFLOAD_BUFFER_SPLIT`` can still be used, and it is configured by ``rte_eth_rxseg_split``. Applied, thanks.
