From: Ben Walker Date: Wed, 11 Jan 2017 17:10:11 +0000 (-0700) Subject: pci: separate detaching ethernet ports from PCI devices X-Git-Tag: spdx-start~5191 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=22dda618c00c;p=dpdk.git pci: separate detaching ethernet ports from PCI devices Attaching and detaching ethernet ports from an application is not the same thing as physically removing a PCI device, so clarify the flags indicating support. All PCI devices are assumed to be physically removable, so no flag is necessary in the PCI layer.
