From c1bbd9900d65ac65b9fce9f129e3369a04871570 Mon Sep 17 00:00:00 2001 From: Pavan Chebbi Date: Thu, 19 Feb 2026 10:53:12 -0800 Subject: [PATCH] bnxt_en: Fix deleting of Ntuple filters Ntuple filters can be deleted when the interface is down. The current code blindly sends the filter delete command to FW. When the interface is down, all the VNICs are deleted in the FW. When the VNIC is freed in the FW, all the associated filters are also freed. We need not send the free command explicitly. Sending such command will generate FW error in the dmesg. In order to fix this, we can safely return from bnxt_hwrm_cfa_ntuple_filter_free() when BNXT_STATE_OPEN is not true which confirms the VNICs have been deleted.
