It finds the txq as the same index as rxq. However in some scenarios, specially for flow control the number of rxq and txq can be different. This patch maxes the txq and function of rxq for all such scenario instead of keeping 1:1 relationship between the two. Now packets from all RXQs can be forwarded to TXQs Signed-off-by: Jun Yang --- app/test-pmd/config.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/app/test-pmd/config.c b/app/test-pmd/config.c index d59968278..efa409453 100644 --- a/app/test-pmd/config.c +++ b/app/test-pmd/config.c @@ -2130,8 +2130,6 @@ rss_fwd_config_setup(void) streamid_t sm_id; nb_q = nb_rxq; - if (nb_q > nb_txq) - nb_q = nb_txq; cur_fwd_config.nb_fwd_lcores = (lcoreid_t) nb_fwd_lcores; cur_fwd_config.nb_fwd_ports = nb_fwd_ports; cur_fwd_config.nb_fwd_streams = @@ -2154,7 +2152,7 @@ rss_fwd_config_setup(void) fs->rx_port = fwd_ports_ids[rxp]; fs->rx_queue = rxq; fs->tx_port = fwd_ports_ids[txp]; - fs->tx_queue = rxq; + fs->tx_queue = (rxq % nb_txq); fs->peer_addr = fs->tx_port; fs->retry_enabled = retry_enabled; rxp++; -- 2.17.1
