Subject: [PATCH] net/bonding: fix RSS not work for bonding


RSS don't work when upgrade to DPDK21.11.


e.g.:

examples/bond/main.c:

conf:

static struct rte_eth_conf port_conf = {

.rxmode = {

.mq_mode = RTE_ETH_MQ_RX_NONE,

.split_hdr_size = 0,

},

.rx_adv_conf = {

.rss_conf = {

.rss_key = NULL,

.rss_hf = RTE_ETH_RSS_IP,

},

},

.txmode = {

.mq_mode = RTE_ETH_MQ_TX_NONE,

},

};


call chain:

rte_eth_bond_create()->rte_eth_dev_configure()->rte_eth_bond_slave_add()->rte_eth_dev_start()
