Subject: [PATCH 2/2] s390/pci: skip VF scanning
Date: Tue, 18 Dec 2018 11:16:50 +0100	[thread overview]
Message-ID: <20181218101650.23089-2-sebott@linux.ibm.com> (raw)
In-Reply-To: <20181217173546.GA4106@infradead.org>

Set the flag to skip scanning for VFs after SRIOV enablement.
VF creation will be triggered by the hotplug code.
