From mboxrd@z Thu Jan 1 00:00:00 1970 From: Auke Kok Subject: [PATCH 1/6] e1000e: update netstats traffic counters realtime Date: Tue, 13 Nov 2007 15:11:10 -0800 Message-ID: <20071113231110.13177.27339.stgit@localhost.localdomain> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Cc: netdev@vger.kernel.org, jesse.brandeburg@intel.com, auke-jan.h.kok@intel.com To: davem@davemloft.net, jeff@garzik.org Return-path: Received: from mga02.intel.com ([134.134.136.20]:39179 "EHLO mga02.intel.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1762968AbXKMXQt (ORCPT ); Tue, 13 Nov 2007 18:16:49 -0500 Sender: netdev-owner@vger.kernel.org List-Id: netdev.vger.kernel.org formerly e1000/e1000e only updated traffic counters once every 2 seconds with the register values of bytes/packets. With newer code however in the interrupt and polling code we can real-time fill in these values in the netstats struct for users to see.
