From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Matt Carlson" Subject: [PATCH net-next 04/13] tg3: Fix IPv6 TCP problems for 5719 Date: Thu, 19 May 2011 15:12:47 -0700 Message-ID: <1305843176-32358-5-git-send-email-mcarlson@broadcom.com> Mime-Version: 1.0 Content-Type: text/plain Content-Transfer-Encoding: 7bit Cc: netdev@vger.kernel.org, mcarlson@broadcom.com To: davem@davemloft.net Return-path: Received: from mms1.broadcom.com ([216.31.210.17]:1098 "EHLO mms1.broadcom.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S934865Ab1ESVxY (ORCPT ); Thu, 19 May 2011 17:53:24 -0400 Sender: netdev-owner@vger.kernel.org List-ID: Commit 4d163b75e979833979cc401ae433cb1d7743d57e, entitled "tg3: Fix 5719 A0 tx completion bug" turned off TSO to fix a hardware bug. In doing so, it accidentally turned off all IPv6 TCP checksum offloading too. This patch fixes the problem by reenabling the hardware bit that control both features. The TSO capability is still not exposed to the kernel.
