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

My order of configuration is as follows: 1. Enable .rxmode.mq_mode = ETH_MQ_RX_RSS 2. Initialize port by rte_eth_dev_configure() 3. Setup multiple Rxqueues for a single port by calling rte_eth_rx_queue_setup() on each queueid. 4.setup a single txqueue by rte_eth_tx_queue_setup() 5. start the device with rte_eth_dev_start() 6. Configure rte_flow with pattern -> flow create port0 ingress pattern eth / end / action RSS on multiple queues / end 7. Add Mac address 8. Check the port link status If I try to configure rte_flow before calling rte_eth_dev_start, I get the error message "net_mlx5: port 0 is not started when inserting a flow and rte_flow_create() returns NULL ". Also i enabled debug logging with "--log-level=*:debug", but don't see any errors for flow validation/ flow creation . Please let me know if I'm missing something, or need to add any other configurations?

To make it work you can do either adding ip layer to the items to make the RSS happen on L3 or simply through the rss types of the rss action which would cause an automatic expansion for the items in mlx5 pmd internally.
