Message-ID: <1314827094-29714-3-git-send-email-mcarlson@broadcom.com> Date: Wed, 31 Aug 2011 14:44:48 -0700 From: "Matt Carlson" <mcarlson@...adcom.com> To: davem@...emloft.net cc: netdev@...r.kernel.org, mcarlson@...adcom.com Subject: [PATCH net-next 2/8] tg3: Fix missed MSI workaround This patch fixes a minor counter initialization bug and makes the MSI workaround slightly more efficient by attempting to service pending interrupts before applying the workaround.
