The root cause of this bug was setting too many\nTC queue pairs on huge multiprocessor machines. When quantity of the\nTC queue pairs is exceeding MSI-X vectors count then TX queue number\ncan be selected beyond actual TX queues amount.\n\nSigned-off-by: Paweł Jabłoński <pawel.jablonski@intel.com>\n---\n drivers/net/ethernet/intel/i40e/i40e_main.c | 4 ++++\n 1 file changed, 4 insertions(+)", "diff": "diff --git a/drivers/net/ethernet/intel/i40e/i40e_main.c b/drivers/net/ethernet/intel/i40e/i40e_main.c\nindex 14e4a2b..ea8be7c 100644\n--- a/drivers/net/ethernet/intel/i40e/i40e_main.c\n+++ b/drivers/net/ethernet/intel/i40e/i40e_main.c\n@@ -1811,6 +1811,10 @@ static void i40e_vsi_setup_queue_map(struct i40e_vsi *vsi,\n \tnum_tc_qps = qcount / numtc;\n \tnum_tc_qps = min_t(int, num_tc_qps, i40e_pf_get_max_q_per_tc(pf));\n \n+\t/* Do not allow use more TC queue pairs than MSI-X vectors exist */\n+\tif (pf->flags & I40E_FLAG_MSIX_ENABLED)\n+\t\tnum_tc_qps = min_t(int, num_tc_qps, pf->num_lan_msix);\n+\n \t/* Setup queue offset/count for all TCs for given VSI */\n \tfor (i = 0; i < I40E_MAX_TRAFFIC_CLASS; i++) {\n \t\t/* See if the given TC is enabled for the given VSI */\n", "prefixes": [ "next", "S85-V1", "03/14" ] }
