Date: Fri, 19 Oct 2007 14:36:53 -0700 From: "Matt Carlson" <mcarlson@...adcom.com> To: davem@...emloft.net cc: netdev@...r.kernel.org, andy@...yhouse.net, "Michael Chan" <mchan@...adcom.com> Subject: [PATCH 4/7] tg3: PCI command adjustment This patch changes the way the driver works with the PCI command register. It adjusts the access size from dwords to words. This patch is done both as a PCI configuration space cleanup and as preparatory work for PCI error recovery.
