Subject: [PATCH] net/bonding: fix RSS not work for bonding
RSS don39t 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()

The key is the API call sequence about bond_ethdev_configure and rte_eth_bond_slave_add. testpmd ensure that rte_eth_bond_slave_add is first called before bond_ethdev_configure, so this is no bug. Of course I also agree with this patch.
