From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jeff Kirsher Subject: [PATCH] igb/ixgbe/e1000e: resolve tx multiqueue bug Date: Fri, 18 Jul 2008 04:02:25 -0700 Message-ID: <20080718110225.20696.14881.stgit@localhost.localdomain> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Cc: netdev@vger.kernel.org To: davem@davemloft.net Return-path: Received: from mga03.intel.com ([143.182.124.21]:63573 "EHLO mga03.intel.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751995AbYGRLC1 (ORCPT ); Fri, 18 Jul 2008 07:02:27 -0400 Sender: netdev-owner@vger.kernel.org List-ID: With the recent changes to tx mutiqueue, igb/ixgbe/e1000e was not calling netif_tx_start_all_queues() before calling netif_tx_wake_all_queues(). This causes an issue during loading of the driver. In addition, updated e1000e to use the updated tx mutliqueue api.
