It is useful in some scenarios,\nsuch as GPU acceleration. The splitting will help to enable true zero\ncopy and hence improve the performance significantly.\n\nThis patchset extends the current buffer split to support multi protocol\nheaders split. When Rx queue is configured with buffer split feature,\npackets received will be directly splitted into two different mempools.\n\nv6->v7:\n*fix supported header protocol check.\n*add rxhdrs commands and parameters.\nv5->v6:\n*Change doc and designi of struct rte_eth_rxseg_split, support multi\nsegments protocol_hdr configuration.\nv4->v5:\n* Use protocol and mbuf_offset based buffer split instead of header split.\n* Use RTE_PTYPE* instead of enum rte_eth_rx_header_split_protocol_type.\n* Improve the description of rte_eth_rxseg_split.proto.\n\nv3->v4:\n* Use RTE_ETH_RX_HEADER_SPLIT_NONE instead of 0.\n\nv2->v3:\n* Fix a PMD bug.\n* Add rx queue header split check.\n* Revise the log and doc.\n\nv1->v2:\n* Add support for all header split protocol types.\n\nWenxuan Wu (3):\n ethdev: introduce protocol header based buffer split\n net/ice: support buffer split in Rx path\n app/testpmd: add rxhdrs commands and parameters\n\n app/test-pmd/cmdline.c | 127 ++++++++++++++-\n app/test-pmd/config.c | 81 ++++++++++\n app/test-pmd/parameters.c | 15 +-\n app/test-pmd/testpmd.c | 6 +-\n app/test-pmd/testpmd.h | 6 +\n drivers/net/ice/ice_ethdev.c | 10 +-\n drivers/net/ice/ice_rxtx.c | 220 ++++++++++++++++++++++----\n drivers/net/ice/ice_rxtx.h | 16 ++\n drivers/net/ice/ice_rxtx_vec_common.h | 3 +\n lib/ethdev/rte_ethdev.c | 40 ++++-\n lib/ethdev/rte_ethdev.h | 28 +++-\n 11 files changed, 505 insertions(+), 47 deletions(-)" }
