This behaviour is correct. Afterwards\n> existing filter can be removed making free slot for the new one. This\n> however causes the newly added filter to be accepted by firmware but\n> removed from driver filter list resulting in not showing after issuing 'ethtool -\n> n <dev_name>'.\n> \n> This happended due to not clearing the variable pf->fd_inv which stores filter\n> number to be removed from the list when firmware refused to add the\n> requested filter. It caused the filter with this specific ID to be constantly\n> removed once it was added to the list although it has been accepted by\n> firmware and effectively applied to the NIC.\n> It was fixed by clearing pf->fd_inv variable after removal of the filter from\n> the list when it was rejected by firmware.\n> \n> Signed-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(+)\n\nTested-by: Andrew Bowers <andrewx.bowers@intel.com>","headers":{"Return-Path":"<intel-wired-lan-bounces@osuosl.org>","X-Original-To":["incoming@patchwork.ozlabs.org","intel-wired-lan@lists.osuosl.org"],"Delivered-To":["patchwork-incoming@bilbo.ozlabs.org","intel-wired-lan@lists.osuosl.org"],"Authentication-Results":"ozlabs.org;\n\tspf=pass (mailfrom) smtp.mailfrom=osuosl.org\n\t(client-ip=140.211.166.136;
