Date: Thu, 8 Oct 2009 08:16:43 +0800 From: Thomas Chou <thomas@...ron.com.tw> To: netdev@...r.kernel.org Cc: thierry.reding@...onic-design.de, Nios2 development list <nios2-dev@...c.et.ntust.edu.tw>, linux-kernel@...r.kernel.org, Thomas Chou <thomas@...ron.com.tw> Subject: [PATCH 2/2] ethoc: clear only pending irqs This patch fixed the problem of dropped packets due to lost of interrupt requests. We should only clear what was pending at the moment we read the irq source reg.
