From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jeff Kirsher Subject: [net-next 07/11] igb: retire the RX_CSUM flag and use the netdev flag instead Date: Fri, 7 Oct 2011 23:47:37 -0700 Message-ID: <1318056461-19562-8-git-send-email-jeffrey.t.kirsher@intel.com> References: <1318056461-19562-1-git-send-email-jeffrey.t.kirsher@intel.com> Cc: Alexander Duyck , netdev@vger.kernel.org, gospo@redhat.com, sassmann@redhat.com, Jeff Kirsher To: davem@davemloft.net Return-path: Received: from mga03.intel.com ([143.182.124.21]:16687 "EHLO mga03.intel.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751450Ab1JHGrs (ORCPT ); Sat, 8 Oct 2011 02:47:48 -0400 In-Reply-To: <1318056461-19562-1-git-send-email-jeffrey.t.kirsher@intel.com> Sender: netdev-owner@vger.kernel.org List-ID: From: Alexander Duyck Since the netdev now has its' own checksum flag to indicate if Rx checksum is enabled we might as well use that instead of using the ring flag.
