The following sequences was working fine on mlx5:
rte_eth_dev_configure(portid, ...);
for (queueid = 0; queueid < nb_txq; queueid++)
rte_eth_tx_queue_setup(portid, queueid, ...);
for (queueid = 0; queueid < nb_rxq; queueid++)
rte_eth_rx_queue_setup(portid, queueid, ...);
// use a custom reta configuration
rte_eth_dev_rss_reta_update(portid, reta_conf, reta_size);
rte_eth_dev_start(portid);
We were able to configure a custom reta before starting the port.
The commit "net/mlx5: support RSS on hairpin" breaks this logic by
moving the code initializing the RSS reta from rte_eth_dev_configure
into rte_eth_dev_start.
To fix the issue, the skip_default_rss_reta is always set to 1 in
rte_eth_dev_rss_reta to avoid reconfigure the rss reta when the device
is started.
