hi
I am using the dpdk bond of mlx5. There is a segment error in the
process of starting the bond port. This is because EAL interrupt thread
is processing LSC interrupt when slave_configure is executing the
rte_eth_dev_rss_reta_update. rte_eth_dev_rss_reta_update will also use
mlx5 flow list.
I've also found another discussion about this
issue.https://mails.dpdk.org/archives/dev/2019-March/125929.html

Do it need a lock to protect the mlx5 flow list?
int
slave_configure(struct rte_eth_dev *bonded_eth_dev,
struct rte_eth_dev *slave_eth_dev)
{
...
/* Start device */
errval = rte_eth_dev_start(slave_eth_dev->data->port_id);
if (errval != 0) {
RTE_BOND_LOG(ERR, "rte_eth_dev_start: port=%u, err (%d)",
slave_eth_dev->data->port_id, errval);
return -1;
}
/* If RSS is enabled for bonding, synchronize RETA */
if (bonded_eth_dev->data->dev_conf.rxmode.mq_mode & ETH_MQ_RX_RSS) {
int i;
struct bond_dev_private *internals;
internals = bonded_eth_dev->data->dev_private;
for (i = 0; i < internals->slave_count; i++) {
if (internals->slaves[i].port_id ==
slave_eth_dev->data->port_id) {
errval = rte_eth_dev_rss_reta_update(
slave_eth_dev->data->port_id,
&internals->reta_conf[0],
internals->slaves[i].reta_size);
if (errval != 0) {
RTE_BOND_LOG(WARNING,
"rte_eth_dev_rss_reta_update on slave port
%d fails (err %d)."
" RSS Configuration for bonding may be
inconsistent.",
slave_eth_dev->data->port_id, errval);
}
break;
}
}
}
