When Rx queue is configured with RTE_ETH_RX_OFFLOAD_BUFFER_SPLIT\noffload and corresponding protocol, packets received will be directly split\ninto different mempools.\n\nChange log:\nv7:\nice: Fix CI issue.\n\nv6:\nice: Fix proto_hdr mappings to NIC configuration.\n\nv5:\nDefine proto_hdr to use mask instead of single protocol type.\nDefine PMD to return protocol header mask.\nRefine the doc and commit log.\nRemove deprecated RTE_FUNC_PTR_OR_ERR_RET.\n\nv4:\nChange proto_hdr to a bit mask of RTE_PTYPE_*.\nAdd the description on how to put the unsplit packages.\nUse proto_hdr to determine whether to use protocol based split.\n\nv3:\nFix mail thread.\n\nv2:\nAdd mbuf dump to the driver's buffer split path.\nAdd buffer split to the driver feature list.\nRemove unsupported header protocols from the driver.\n\nYuan Wang (4):\n ethdev: introduce protocol header API\n ethdev: introduce protocol hdr based buffer split\n app/testpmd: add rxhdrs commands and parameters\n net/ice: support buffer split in Rx path\n\n app/test-pmd/cmdline.c | 146 +++++++++++++-\n app/test-pmd/config.c | 88 +++++++++\n app/test-pmd/parameters.c | 16 +-\n app/test-pmd/testpmd.c | 2 +\n app/test-pmd/testpmd.h | 6 +\n doc/guides/rel_notes/release_22_11.rst | 16 ++\n drivers/net/ice/ice_ethdev.c | 55 +++++-\n drivers/net/ice/ice_rxtx.c | 259 ++++++++++++++++++++++---\n drivers/net/ice/ice_rxtx.h | 16 ++\n drivers/net/ice/ice_rxtx_vec_common.h | 3 +\n lib/ethdev/ethdev_driver.h | 15 ++\n lib/ethdev/rte_ethdev.c | 107 ++++++++--\n lib/ethdev/rte_ethdev.h | 59 +++++-\n lib/ethdev/version.map | 3 +\n 14 files changed, 743 insertions(+), 48 deletions(-)" }
