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: 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.
