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()
