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()

Cannot get your meaning, Why RSS don't work?
As mq_mode is not RTE_ETH_MQ_RX_RSS in rte_eth_conf, RSS is off.
Please make it clearer, thanks.

Sorry，mq_mode is RTE_ETH_MQ_RX_RSS in rte_eth_conf.
call chain:
rte_eth_bond_create()->rte_eth_dev_configure()->rte_eth_bond_slave_add()->rte_eth_dev_start()
Consider this call chain, internals->rss_key_len is 0 in bond_ethdev_configure() when we call rte_eth_dev_configure().
If internals->rss_key_len is 0, internals->rss_key can not be set properly.
Because memcpy in bond_ethdev_configure() use internals->rss_key_len(it is 0) as copy size, and internals->rss_key will not be set in other functions.
---
e.g.:
bond_ethdev_configure(struct rte_eth_dev *dev)
{
const char *name = dev->device->name
struct bond_dev_private *internals = dev->data->dev_private
...
/*
* If RSS is enabled, fill table with default values and
* set key to the value specified in port RSS configuration.
* Fall back to default RSS key if the key is not specified
*/
if (dev->data->dev_conf.rxmode.mq_mode & RTE_ETH_MQ_RX_RSS) {
struct rte_eth_rss_conf *rss_conf =
&dev->data->dev_conf.rx_adv_conf.rss_conf
if (rss_conf->rss_key != NULL) {
if (internals->rss_key_len > rss_conf->rss_key_len) {
RTE_BOND_LOG(ERR, "Invalid rss key length(%u)",
rss_conf->rss_key_len)
return -EINVAL
}
memcpy(internals->rss_key, rss_conf->rss_key,
internals->rss_key_len)
} else {
if (internals->rss_key_len > sizeof(default_rss_key)) {
RTE_BOND_LOG(ERR,
"There is no suitable default hash key")
return -EINVAL
}
memcpy(internals->rss_key, default_rss_key,
internals->rss_key_len)
}

Have you done any test? Is it true that it doesn't work for RSS? which
NIC you choose ?
As I know, internals->rss_key_len will inherit dev info from slave, just
see "eth_bond_slave_inherit_dev_info_rx_first". If slave port report
hash_key_size, internals->rss_key_len could not be zero.

Hi, I tested Mellanox CX5 and Intel E810.
The key is the call chain:
1.rte_eth_bond_create()
2.rte_eth_dev_configure(): bond_ethdev_configure() //internals->rss_key_len = 0, internals->rss_key can not be set properly
3.rte_eth_bond_slave_add(): __eth_bond_slave_add_lock_free()->eth_bond_slave_inherit_dev_info_rx_first() // internals->rss_key_len will be set, but internals->rss_key is bad
4.rte_eth_dev_start()
examples/bond/main.c(bond_port_init()) use this call chain,too many apps refer to this example.
thanks

Hi,
I got your meaning.
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.
Thanks.

Hi Yu Wenjun,
The patch is not shown in the patchwork, I assume because of its format,
can you please send a new version as text only?
Using 'git send-email' is the easiet way for it, please check:
https://doc.dpdk.org/guides/contributing/patches.html
Also Connor clarifies the issue above, can you please add this detail
about the issue in the next version?
Thanks,
ferruh

Subject: [PATCH] net/bonding: fix RSS not work for bonding
RSS don't work when bond_ethdev_configure called before rte_eth_bond_slave_add in DPDK21.11.
e.g.:
dont't work(examples/bond/main.c):
rte_eth_bond_create()
rte_eth_dev_configure()
rte_eth_bond_slave_add()
rte_eth_dev_start()
work(testpmd):
rte_eth_bond_create()
rte_eth_bond_slave_add()
rte_eth_dev_configure()
rte_eth_dev_start()
