From 395d41fbb1dd2faa21e143865ce12c195ec8194b Mon Sep 17 00:00:00 2001 From: Qiming Chen Date: Fri, 10 Sep 2021 11:12:49 +0800 Subject: [PATCH] common/iavf: fix ARQ resource leak In the iavf_init_arq function, if an exception occurs in the iavf_config_arq_regs function, and the previously applied ARQ (Admin Receive Queue) bufs resource is released. This patch maintains the same modification as the iavf_init_asq function to roll back resources.
