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. This patchset aims to support protocol header 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 different mempools. Change log: v9: Define the intend behaviors for exact match and longest match. Add protocol headers repeat check. Add no proto-split after length-based split check. Add a helper function to short the check function. Refine the doc and commit log. v8: Restrict length == 0 and proto_hdr == 0 in another buffer split. Add check for proto_hdr == 0 in last segment. Use heap instead of stack for array to avoid vulnerabilities. Define the proto_hdr for two segments and multi-segments, respectively. Separate variable definition and code. Refine the doc and commit log. v7: ice: Fix CI issue. v6: ice: Fix proto_hdr mappings to NIC configuration. v5: Define proto_hdr to use mask instead of single protocol type. Define PMD to return protocol header mask. Refine the doc and commit log. Remove deprecated RTE_FUNC_PTR_OR_ERR_RET. v4: Change proto_hdr to a bit mask of RTE_PTYPE_*. Add the description on how to put the unsplit packages. Use proto_hdr to determine whether to use protocol based split. v3: Fix mail thread. v2: Add mbuf dump to the driver's buffer split path. Add buffer split to the driver feature list. Remove unsupported header protocols from the driver.
