This behaviour is correct. Afterwards\nexisting filter can be removed making free slot for the new one. This\nhowever causes the newly added filter to be accepted by firmware but\nremoved from driver filter list resulting in not showing after issuing\n'ethtool -n <dev_name>'.\n\nThis happended due to not clearing the variable pf->fd_inv which stores\nfilter number to be removed from the list when firmware refused to add the\nrequested filter. It caused the filter with this specific ID to be\nconstantly removed once it was added to the list although it has been\naccepted by firmware and effectively applied to the NIC.\nIt was fixed by clearing pf->fd_inv variable after removal of the filter\nfrom the list when it was rejected by firmware.\n\nSigned-off-by: Filip Sadowski <filip.sadowski@intel.com>\n---\n drivers/net/ethernet/intel/i40e/i40e_main.c | 1 +\n 1 file changed, 1 insertion(+)", "diff": "diff --git a/drivers/net/ethernet/intel/i40e/i40e_main.c b/drivers/net/ethernet/intel/i40e/i40e_main.c\nindex b1712b4..2fdd130 100644\n--- a/drivers/net/ethernet/intel/i40e/i40e_main.c\n+++ b/drivers/net/ethernet/intel/i40e/i40e_main.c\n@@ -6233,6 +6233,7 @@ void i40e_fdir_check_and_reenable(struct i40e_pf *pf)\n \t\t\t\thlist_del(&filter->fdir_node);\n \t\t\t\tkfree(filter);\n \t\t\t\tpf->fdir_pf_active_filters--;\n+\t\t\t\tpf->fd_inv = 0;\n \t\t\t}\n \t\t}\n \t}\n", "prefixes": [ "next", "S79-V2", "09/13" ] }
