Message-ID: <20110203172656.GD9024@electric-eye.fr.zoreil.com> Date: Thu, 3 Feb 2011 18:26:56 +0100 From: Francois Romieu <romieu@...zoreil.com> To: davem@...emloft.net Cc: netdev@...r.kernel.org, Ivan Vecera <ivecera@...hat.com>, Hayes Wang <hayeswang@...ltek.com> Subject: [PATCH 3/3] r8169: prevent RxFIFO induced loops in the irq handler. While the RxFIFO interruption is masked for most 8168, nothing prevents it to appear in the irq status word. This is no excuse to crash.
