From mboxrd@z Thu Jan 1 00:00:00 1970 From: Daniel Borkmann Subject: [PATCH net-next 3/5] packet: minor: convert status bits into shifting format Date: Tue, 23 Apr 2013 12:39:30 +0200 Message-ID: <1366713572-11978-4-git-send-email-dborkman@redhat.com> References: <1366713572-11978-1-git-send-email-dborkman@redhat.com> Cc: netdev@vger.kernel.org, willemb@google.com, Paul.Chavent@onera.fr, richardcochran@gmail.com To: davem@davemloft.net Return-path: Received: from mx1.redhat.com ([209.132.183.28]:62856 "EHLO mx1.redhat.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1755708Ab3DWKmp (ORCPT ); Tue, 23 Apr 2013 06:42:45 -0400 In-Reply-To: <1366713572-11978-1-git-send-email-dborkman@redhat.com> Sender: netdev-owner@vger.kernel.org List-ID: This makes it more readable and clearer what bits are still free to use. The compiler reduces this to a constant for us anyway.
