Subject: [pci PATCH v4 3/4] ena: Migrate over to "unmanaged SR-IOV" support
Date: Thu, 08 Mar 2018 11:03:53 -0800	[thread overview]
Message-ID: <20180308190349.5433.8420.stgit@localhost.localdomain> (raw)
In-Reply-To: <20180308185507.5433.98830.stgit@localhost.localdomain>

From: Alexander Duyck <alexander.h.duyck@intel.com>

Instead of implementing our own version of a SR-IOV configuration stub in
the ena driver we can just reuse the existing
pci_sriov_configure_unmanaged function.
