But normally\nthey're no big deal. To assist in assessing this, add a counter to\nour Ethtool stats. A handful of ARQ overflows during VF init is no\nproblem. A large, ever-growing number indicates that Something Bad is\nhappening.\n\nSigned-off-by: Mitch Williams <mitch.a.williams@intel.com>\nChange-ID: Ie5348bfbc8a54a890559cb00279c28d976a55096\n---\n drivers/net/ethernet/intel/i40e/i40e.h | 1 +\n drivers/net/ethernet/intel/i40e/i40e_ethtool.c | 1 +\n drivers/net/ethernet/intel/i40e/i40e_main.c | 1 +\n 3 files changed, 3 insertions(+)", "diff": "diff --git a/drivers/net/ethernet/intel/i40e/i40e.h b/drivers/net/ethernet/intel/i40e/i40e.h\nindex 7ec304c..9ad2f37 100644\n--- a/drivers/net/ethernet/intel/i40e/i40e.h\n+++ b/drivers/net/ethernet/intel/i40e/i40e.h\n@@ -392,6 +392,7 @@ struct i40e_pf {\n \tstruct i40e_vf *vf;\n \tint num_alloc_vfs;\t/* actual number of VFs allocated */\n \tu32 vf_aq_requests;\n+\tu32 arq_overflows;\t/* Not fatal, possibly indicative of problems */\n \n \t/* DCBx/DCBNL capability for PF that indicates\n \t * whether DCBx is managed by firmware or host\ndiff --git a/drivers/net/ethernet/intel/i40e/i40e_ethtool.c b/drivers/net/ethernet/intel/i40e/i40e_ethtool.c\nindex e13ee93..691939d 100644\n--- a/drivers/net/ethernet/intel/i40e/i40e_ethtool.c\n+++ b/drivers/net/ethernet/intel/i40e/i40e_ethtool.c\n@@ -143,6 +143,7 @@ static struct i40e_stats i40e_gstrings_stats[] = {\n \tI40E_PF_STAT(\"rx_oversize\", stats.rx_oversize),\n \tI40E_PF_STAT(\"rx_jabber\", stats.rx_jabber),\n \tI40E_PF_STAT(\"VF_admin_queue_requests\", vf_aq_requests),\n+\tI40E_PF_STAT(\"arq_overflows\", arq_overflows),\n \tI40E_PF_STAT(\"rx_hwtstamp_cleared\", rx_hwtstamp_cleared),\n \tI40E_PF_STAT(\"fdir_flush_cnt\", fd_flush_cnt),\n \tI40E_PF_STAT(\"fdir_atr_match\", stats.fd_atr_match),\ndiff --git a/drivers/net/ethernet/intel/i40e/i40e_main.c b/drivers/net/ethernet/intel/i40e/i40e_main.c\nindex 66cc702..f751a80 100644\n--- a/drivers/net/ethernet/intel/i40e/i40e_main.c\n+++ b/drivers/net/ethernet/intel/i40e/i40e_main.c\n@@ -6242,6 +6242,7 @@ static void i40e_clean_adminq_subtask(struct i40e_pf *pf)\n \t\tif (hw->debug_mask & I40E_DEBUG_AQ)\n \t\t\tdev_info(&pf->pdev->dev, \"ARQ Overflow Error detected\\n\");\n \t\tval &= ~I40E_PF_ARQLEN_ARQOVFL_MASK;\n+\t\tpf->arq_overflows++;\n \t}\n \tif (val & I40E_PF_ARQLEN_ARQCRIT_MASK) {\n \t\tif (hw->debug_mask & I40E_DEBUG_AQ)\n", "prefixes": [ "next", "S25", "08/16" ] }
