From eac901ce29be559b1bb5c5da33fe2bf5c0b4bfd6 Mon Sep 17 00:00:00 2001
From: Jan Blunck <jblunck@infradead.org>
Date: Fri, 23 Dec 2016 16:58:11 +0100
Subject: [PATCH] ethdev: decouple from PCI device

This makes struct rte_eth_dev independent of struct rte_pci_device by
replacing it with a pointer to the generic struct rte_device.
