The splitting will help to enable true zero copy and hence +improve the performance significantly. + +It supports protocol 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 two different mempools with expected hdr and payload length/content. + +For validation, we will focus on: +1.
