Message-ID: <1329182417-28223-2-git-send-email-mcarlson@broadcom.com> Date: Mon, 13 Feb 2012 17:20:08 -0800 From: "Matt Carlson" <mcarlson@...adcom.com> To: davem@...emloft.net cc: netdev@...r.kernel.org, mcarlson@...adcom.com, mchan@...adcom.com Subject: [PATCH net-next 01/10] tg3: Disable new DMA engine for 57766 A bug was found in the new DMA engine for the 57766. This patch disables it, which causes the device to fallback to the old DMA engine.
