From mboxrd@z Thu Jan 1 00:00:00 1970 From: Gaetan Rivet Subject: [PATCH v5 02/12] ethdev: add deferred intermediate device state Date: Thu, 8 Jun 2017 01:59:52 +0200 Message-ID: <484662a7b2946d94935e9bfad437cda2e4c37d62.1496877105.git.gaetan.rivet@6wind.com> References: Cc: Gaetan Rivet To: dev@dpdk.org Return-path: Received: from mail-wm0-f42.google.com (mail-wm0-f42.google.com [74.125.82.42]) by dpdk.org (Postfix) with ESMTP id E209B7CAC for ; Thu, 8 Jun 2017 02:00:16 +0200 (CEST) Received: by mail-wm0-f42.google.com with SMTP id d73so20780788wma.0 for ; Wed, 07 Jun 2017 17:00:16 -0700 (PDT) In-Reply-To: In-Reply-To: References: 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 device state means that the device is managed externally, by whichever party has set this state (PMD or application). Note: this new device state is only an information. The related device structure and operators are still valid and can be used normally. It is however made private by device management helpers within ethdev, making the device invisible to applications.
