From: Olivier Matz Date: Fri, 11 Apr 2014 11:45:03 +0000 (+0200) Subject: vdev: rename nonpci_devs as vdev X-Git-Tag: spdx-start~10890 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=9fa5e2b026d18319be6fde18e08b6842937802a1;p=dpdk.git vdev: rename nonpci_devs as vdev The name "nonpci_devs" for virtual devices is ambiguous as a physical device can also be non-PCI (ex: usb, sata, ...). A better name for this file is "vdev" as it only deals with virtual devices. This patch doesn't introduce any change except renaming.
