Otherwise, queue index being\nused can go out of range.\n\nFor example, when vsi->alloc_txq has 104 queues and with 3 TCS enabled\nvia DCB, each TC gets 34 queues, vsi->num_txq will be 102 and only 102\nqueues will be enabled.\n\nSigned-off-by: Usha Ketineni <usha.k.ketineni@intel.com>\n---\n drivers/net/ethernet/intel/ice/ice_ethtool.c | 14 +++++++-------\n 1 file changed, 7 insertions(+), 7 deletions(-)", "diff": "diff --git a/drivers/net/ethernet/intel/ice/ice_ethtool.c b/drivers/net/ethernet/intel/ice/ice_ethtool.c\nindex 67d884e27ea4..3b9d33ad23d8 100644\n--- a/drivers/net/ethernet/intel/ice/ice_ethtool.c\n+++ b/drivers/net/ethernet/intel/ice/ice_ethtool.c\n@@ -2743,14 +2743,14 @@ ice_set_ringparam(struct net_device *netdev, struct ethtool_ringparam *ring)\n \tnetdev_info(netdev, \"Changing Tx descriptor count from %d to %d\\n\",\n \t\t vsi->tx_rings[0]->count, new_tx_cnt);\n \n-\ttx_rings = devm_kcalloc(&pf->pdev->dev, vsi->alloc_txq,\n+\ttx_rings = devm_kcalloc(&pf->pdev->dev, vsi->num_txq,\n \t\t\t\tsizeof(*tx_rings), GFP_KERNEL);\n \tif (!tx_rings) {\n \t\terr = -ENOMEM;\n \t\tgoto done;\n \t}\n \n-\tfor (i = 0; i < vsi->alloc_txq; i++) {\n+\tice_for_each_txq(vsi, i) {\n \t\t/* clone ring and setup updated count */\n \t\ttx_rings[i] = *vsi->tx_rings[i];\n \t\ttx_rings[i].count = new_tx_cnt;\n@@ -2803,14 +2803,14 @@ ice_set_ringparam(struct net_device *netdev, struct ethtool_ringparam *ring)\n \tnetdev_info(netdev, \"Changing Rx descriptor count from %d to %d\\n\",\n \t\t vsi->rx_rings[0]->count, new_rx_cnt);\n \n-\trx_rings = devm_kcalloc(&pf->pdev->dev, vsi->alloc_rxq,\n+\trx_rings = devm_kcalloc(&pf->pdev->dev, vsi->num_rxq,\n \t\t\t\tsizeof(*rx_rings), GFP_KERNEL);\n \tif (!rx_rings) {\n \t\terr = -ENOMEM;\n \t\tgoto done;\n \t}\n \n-\tfor (i = 0; i < vsi->alloc_rxq; i++) {\n+\tice_for_each_rxq(vsi, i) {\n \t\t/* clone ring and setup updated count */\n \t\trx_rings[i] = *vsi->rx_rings[i];\n \t\trx_rings[i].count = new_rx_cnt;\n@@ -2848,7 +2848,7 @@ ice_set_ringparam(struct net_device *netdev, struct ethtool_ringparam *ring)\n \t\tice_down(vsi);\n \n \t\tif (tx_rings) {\n-\t\t\tfor (i = 0; i < vsi->alloc_txq; i++) {\n+\t\t\tice_for_each_txq(vsi, i) {\n \t\t\t\tice_free_tx_ring(vsi->tx_rings[i]);\n \t\t\t\t*vsi->tx_rings[i] = tx_rings[i];\n \t\t\t}\n@@ -2856,7 +2856,7 @@ ice_set_ringparam(struct net_device *netdev, struct ethtool_ringparam *ring)\n \t\t}\n \n \t\tif (rx_rings) {\n-\t\t\tfor (i = 0; i < vsi->alloc_rxq; i++) {\n+\t\t\tice_for_each_rxq(vsi, i) {\n \t\t\t\tice_free_rx_ring(vsi->rx_rings[i]);\n \t\t\t\t/* copy the real tail offset */\n \t\t\t\trx_rings[i].tail = vsi->rx_rings[i]->tail;\n@@ -2890,7 +2890,7 @@ ice_set_ringparam(struct net_device *netdev, struct ethtool_ringparam *ring)\n free_tx:\n \t/* error cleanup if the Rx allocations failed after getting Tx */\n \tif (tx_rings) {\n-\t\tfor (i = 0; i < vsi->alloc_txq; i++)\n+\t\tice_for_each_txq(vsi, i)\n \t\t\tice_free_tx_ring(&tx_rings[i]);\n \t\tdevm_kfree(&pf->pdev->dev, tx_rings);\n \t}\n", "prefixes": [ "S32", "v2", "05/15" ] }
