Change the condition check to\nallow for excess vectors. In this case, the extras just won't be used.\n\nSigned-off-by: Mitch Williams <mitch.a.williams@intel.com>\nChange-ID: I23e1e2955c64739c86612db88a25583e6a7e0b17\n---\n drivers/net/ethernet/intel/i40evf/i40evf_main.c | 2 +-\n 1 file changed, 1 insertion(+), 1 deletion(-)", "diff": "diff --git a/drivers/net/ethernet/intel/i40evf/i40evf_main.c b/drivers/net/ethernet/intel/i40evf/i40evf_main.c\nindex 37e66ec..23a81da 100644\n--- a/drivers/net/ethernet/intel/i40evf/i40evf_main.c\n+++ b/drivers/net/ethernet/intel/i40evf/i40evf_main.c\n@@ -405,7 +405,7 @@ static int i40evf_map_rings_to_vectors(struct i40evf_adapter *adapter)\n \t/* The ideal configuration...\n \t * We have enough vectors to map one per queue.\n \t */\n-\tif (q_vectors == (rxr_remaining * 2)) {\n+\tif (q_vectors >= (rxr_remaining * 2)) {\n \t\tfor (; rxr_idx < rxr_remaining; v_start++, rxr_idx++)\n \t\t\ti40evf_map_vector_to_rxq(adapter, v_start, rxr_idx);\n \n", "prefixes": [ "net-next", "S5", "02/15" ] }
