Generic Receive Offload (GRO) is a widely used SW-based offloading technique to reduce per-packet processing overhead. It gains performance by reassembling small packets into large ones. This patchset is to support GRO in DPDK. To support GRO, this patch implements a GRO API framework. To enable more flexibility to applications, DPDK GRO is implemented as a user library. Applications explicitly use the GRO library to merge small packets into large ones. DPDK GRO provides two reassembly modes. One is called lightweight mode, the other is called heavyweight mode. If applications want to merge packets in a simple way and the number of packets is relatively small, they can use the lightweight mode. If applications need more fine-grained controls, they can choose the heavyweight mode. rte_gro_reassemble_burst is the main reassembly API which is used in lightweight mode and processes N packets at a time. For applications, performing GRO in lightweight mode is simple. They just need to invoke rte_gro_reassemble_burst. Applications can get GROed packets as soon as rte_gro_reassemble_burst returns. rte_gro_reassemble is the main reassembly API which is used in heavyweight mode and tries to merge N inputted packets with the packets in GRO reassembly tables. For applications, performing GRO in heavyweight mode is relatively complicated. Before performing GRO, applications need to create a GRO context object, which keeps reassembly tables of desired GRO types, by rte_gro_ctx_create. Then applications can use rte_gro_reassemble to merge packets. The GROed packets are in the reassembly tables of the GRO context object. If applications want to get them, applications need to manually flush them by flush API. Signed-off-by: Jiayu Hu <jiayu.hu@intel.com> Reviewed-by: Jianfeng Tan <jianfeng.tan@intel.com>
