We don't\nwant to do this. If the user has changed the RSS settings to use more\nqueues then CPUS, we want to trust they know what they are doing and\nlet them. More importantly, if we tell them that is what we did, we want\nto actually do it and allow traffic into all of the queues we have\nallocated. This does not change the default setting to initially\nallocate only the number of CPUS of queue pairs.\n\nSigned-off-by: Catherine Sullivan <catherine.sullivan@intel.com>\nChange-ID: Ie941a96e806e4bcd016addb4e17affb46770ada5\n---\nTesting Hints: Make sure that RSS can hit all queues up to the maximum\nfor XL710,X710,X722, including a NPAR nic.\n\n drivers/net/ethernet/intel/i40e/i40e_main.c | 10 ++--------\n 1 file changed, 2 insertions(+), 8 deletions(-)", "diff": "diff --git a/drivers/net/ethernet/intel/i40e/i40e_main.c b/drivers/net/ethernet/intel/i40e/i40e_main.c\nindex ae4d089..b749b46 100644\n--- a/drivers/net/ethernet/intel/i40e/i40e_main.c\n+++ b/drivers/net/ethernet/intel/i40e/i40e_main.c\n@@ -1584,14 +1584,8 @@ static void i40e_vsi_setup_queue_map(struct i40e_vsi *vsi,\n \tvsi->tc_config.numtc = numtc;\n \tvsi->tc_config.enabled_tc = enabled_tc ? enabled_tc : 1;\n \t/* Number of queues per enabled TC */\n-\t/* In MFP case we can have a much lower count of MSIx\n-\t * vectors available and so we need to lower the used\n-\t * q count.\n-\t */\n-\tif (pf->flags & I40E_FLAG_MSIX_ENABLED)\n-\t\tqcount = min_t(int, vsi->alloc_queue_pairs, pf->num_lan_msix);\n-\telse\n-\t\tqcount = vsi->alloc_queue_pairs;\n+\tqcount = vsi->alloc_queue_pairs;\n+\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", "prefixes": [ "next", "S37", "11/15" ] }
