From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jeff Kirsher Subject: [net 2/2] ixgbevf: ixgbevf_write/read_posted_mbx should use IXGBE_ERR_MBX to initialize ret_val Date: Wed, 29 Jun 2016 09:30:04 -0700 Message-ID: <1467217804-137463-3-git-send-email-jeffrey.t.kirsher@intel.com> References: <1467217804-137463-1-git-send-email-jeffrey.t.kirsher@intel.com> Cc: Xin Long , netdev@vger.kernel.org, nhorman@redhat.com, sassmann@redhat.com, jogreene@redhat.com, Jeff Kirsher To: davem@davemloft.net Return-path: Received: from mga02.intel.com ([134.134.136.20]:14828 "EHLO mga02.intel.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751376AbcF2Qbn (ORCPT ); Wed, 29 Jun 2016 12:31:43 -0400 In-Reply-To: <1467217804-137463-1-git-send-email-jeffrey.t.kirsher@intel.com> Sender: netdev-owner@vger.kernel.org List-ID: From: Xin Long Now ixgbevf_write/read_posted_mbx use -IXGBE_ERR_MBX as the initiative return value, but it's incorrect, cause in ixgbevf_vlan_rx_add_vid(), it use err == IXGBE_ERR_MBX, the err returned from mac.ops.set_vfta, and in ixgbevf_set_vfta_vf, it return from write/read_posted. so we should initialize err with IXGBE_ERR_MBX, instead of -IXGBE_ERR_MBX. With this fix, the other functions that called it also can work well, cause they only care about if err is 0 or not.
