Hi Helin,
Thanks a lot for your great help, all of rx queue
received network packet after I update rss_hf
from "ETH_RSS_IP" to " ETH_RSS_PROTO_MASK ".
static struct rte_eth_conf port_conf = {
.rxmode = {
.mq_mode = ETH_MQ_RX_RSS,
.max_rx_pkt_len = ETHER_MAX_LEN,
.split_hdr_size = 0,
.header_split = 0, /**< Header Split disabled */
.hw_ip_checksum = 1, /**< IP checksum offload enabled */
.hw_vlan_filter = 0, /**< VLAN filtering disabled */
.jumbo_frame = 0, /**< Jumbo Frame Support disabled */
.hw_strip_crc = 0, /**< CRC stripped by hardware */
},
.rx_adv_conf = {
.rss_conf = {
.rss_key = NULL,
.rss_hf = ETH_RSS_PROTO_MASK,
},
},
.txmode = {
.mq_mode = ETH_MQ_TX_NONE,
},
.fdir_conf.mode = RTE_FDIR_MODE_SIGNATURE,
};
Regards,
Haifeng

Could you help to list the DPDK version you are using now?
Two possible reasons:
1. UDP rss is not enabled on your board correctly.
I40e has different rss flags from ixgbe, so I am wondering if you
use it correctly.
In addition, this will be unified from 2.0. So I care about the DPDK
version.
2. The UDP stream is occasionally hit the hash key of queue 0.
You'd better to try to send your UDP stream with random 5-tuples, to
get the
hash value hit different queues randomly.
