Hi, I'm trying to use rte_flow_action_type_rss to distribute packets all of the same flow type among multiple Rx queues on a single port. Mellanox ConnectX-5 Ex and DPDK version 20.05 is used for this purpose. It doesn't seem to work and all the packets are sent only to a single queue. My queries are : 1. What am I missing or doing differently? 2. Should I be doing any other configurations in rte_eth_conf or rte_eth_rxmode?
My rte_flow configurations: struct rte_flow_item pattern[MAX_RTE_FLOW_PATTERN] = {}; struct rte_flow_action action[MAX_RTE_FLOW_ACTIONS] = {}; struct rte_flow_attr attr; struct rte_flow_item_eth eth; struct rte_flow *flow = NULL; struct rte_flow_error error; int ret; int no_queues =2; uint16_t queues[2]; struct rte_flow_action_rss rss; memset(&error, 0x22, sizeof(error)); memset(&attr, 0, sizeof(attr)); attr.egress = 0; attr.ingress = 1; memset(&pattern, 0, sizeof(pattern)); memset(&action, 0, sizeof(action)); /* setting the eth to pass all packets */ pattern[0].type = RTE_FLOW_ITEM_TYPE_ETH; pattern[0].spec = ð pattern[1].type = RTE_FLOW_ITEM_TYPE_END; rss.types = ETH_RSS_IP; rss.level = 0; rss.func = RTE_ETH_HASH_FUNCTION_TOEPLITZ; rss.key_len =0; rss.key = NULL; rss.queue_num = no_queues; for (int i= 0; i < no_queues; i++){ queues[i] = i; } rss.queue = queues; action[0].type = RTE_FLOW_ACTION_TYPE_RSS; action[0].conf = &rss; action[1].type = RTE_FLOW_ACTION_TYPE_END; ret = rte_flow_validate(portid, &attr, pattern, action, &error); if (ret < 0) { printf( "Flow validation failed %s\n", error.message); return; } flow = rte_flow_create(portid, &attr, pattern, action, &error); if (flow == NULL) printf(" Cannot create Flow create"); And Rx queues configuration: for (int j = 0; j < no_queues; j++) { int ret = rte_eth_rx_queue_setup(portid, j, nb_rxd, rte_eth_dev_socket_id(port_id), NULL,mbuf_pool); if (ret < 0) { printf( "rte_eth_rx_queue_setup:err=%d, port=%u", ret, (unsigned) portid); exit(1); } } Thanks Anna
