Function flow_create_split_outer

dpdk/drivers/net/mlx5/mlx5_flow.c:7286–7301

* Split the flow to subflow set. The splitters might be linked * in the chain, like this: * flow_create_split_outer() calls: * flow_create_split_meter() calls: * flow_create_split_metadata(meter_subflow_0) calls: * flow_create_split_inner(metadata_subflow_0) * flow_create_split_inner(metadata_subflow_1) * flow_create_split_inner(metadata_subflow_2) * flow_create

 *   0 on success, negative value otherwise
