It is necessary to reconfigure all queues every time because configuration can be changed. For example, if we're reconfiguring bonding device with new memory pool, already configured queues will still use the old one. And if the old mempool be freed, application likely will panic in attempt to use freed mempool. This happens when we use the bonding device with OVS 2.6 while MTU reconfiguration: PANIC in rte_mempool_get_ops(): assert "(ops_index >= 0) && (ops_index < RTE_MEMPOOL_MAX_OPS_IDX)" failed Cc: Signed-off-by: Ilya Maximets --- drivers/net/bonding/rte_eth_bond_pmd.c | 10 ++-------- 1 file changed, 2 insertions(+), 8 deletions(-) diff --git a/drivers/net/bonding/rte_eth_bond_pmd.c b/drivers/net/bonding/rte_eth_bond_pmd.c index b20a272..eb5b6d1 100644 --- a/drivers/net/bonding/rte_eth_bond_pmd.c +++ b/drivers/net/bonding/rte_eth_bond_pmd.c @@ -1305,8 +1305,6 @@ slave_configure(struct rte_eth_dev *bonded_eth_dev, struct bond_rx_queue *bd_rx_q; struct bond_tx_queue *bd_tx_q; - uint16_t old_nb_tx_queues = slave_eth_dev->data->nb_tx_queues; - uint16_t old_nb_rx_queues = slave_eth_dev->data->nb_rx_queues; int errval; uint16_t q_id; @@ -1347,9 +1345,7 @@ slave_configure(struct rte_eth_dev *bonded_eth_dev, } /* Setup Rx Queues */ - /* Use existing queues, if any */ - for (q_id = old_nb_rx_queues; - q_id < bonded_eth_dev->data->nb_rx_queues; q_id++) { + for (q_id = 0; q_id < bonded_eth_dev->data->nb_rx_queues; q_id++) { bd_rx_q = (struct bond_rx_queue *)bonded_eth_dev->data->rx_queues[q_id]; errval = rte_eth_rx_queue_setup(slave_eth_dev->data->port_id, q_id, @@ -1365,9 +1361,7 @@ slave_configure(struct rte_eth_dev *bonded_eth_dev, } /* Setup Tx Queues */ - /* Use existing queues, if any */ - for (q_id = old_nb_tx_queues; - q_id < bonded_eth_dev->data->nb_tx_queues; q_id++) { + for (q_id = 0; q_id < bonded_eth_dev->data->nb_tx_queues; q_id++) { bd_tx_q = (struct bond_tx_queue *)bonded_eth_dev->data->tx_queues[q_id]; errval = rte_eth_tx_queue_setup(slave_eth_dev->data->port_id, q_id, -- 2.7.4
