From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ferruh Yigit Subject: [PATCH] ethdev: revert use device name from device structure Date: Fri, 22 Sep 2017 12:30:07 +0100 Message-ID: <20170922113007.43385-1-ferruh.yigit@intel.com> Cc: dev@dpdk.org, Adrien Mazarguil , Ferruh Yigit To: Thomas Monjalon Return-path: Received: from mga06.intel.com (mga06.intel.com [134.134.136.31]) by dpdk.org (Postfix) with ESMTP id 193AD2C24 for ; Fri, 22 Sep 2017 13:30:20 +0200 (CEST) List-Id: DPDK patches and discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dev-bounces@dpdk.org Sender: "dev" This reverts commit a1e7c17555e8f77d520ba5f06ed26c00e77a2bd1. Original commit assumes there is 1:1 mapping between physical device and ethdev port, so that device name can be used per port instead of ethdev name field. But one physical device may have multiple ethdev ports and each port needs its own unique name. One issue reported here: http://dpdk.org/ml/archives/users/2017-September/002484.html So reverting back the commit to continue using ethdev name field per port.
