Message-ID: <20090728085223.GA4977@serverengines.com>
Date: Tue, 28 Jul 2009 14:22:23 +0530
From: Sathya Perla <sathyap@...verengines.com>
To: netdev <netdev@...r.kernel.org>
Subject: [net-next-2.6 PATCH 2/5] be2net: remove pci_func field from
be_adapter struct
pci function is available as PCI_FUNC(pdev->devfn); no need for a
separate field.
