From cb894d99eceb8233bc6555f4cda751940609e778 Mon Sep 17 00:00:00 2001 From: Gaetan Rivet Date: Tue, 18 Jul 2017 14:48:12 +0200 Subject: [PATCH] ethdev: add deferred intermediate device state 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.
