Message-ID: <52B7C590.7070708@huawei.com>
Date: Mon, 23 Dec 2013 13:09:36 +0800
From: Ding Tianhong <dingtianhong@...wei.com>
To: "David S. Miller" <davem@...emloft.net>,
Netdev <netdev@...r.kernel.org>,
"linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org>,
<e1000-devel@...ts.sourceforge.net>
Subject: [PATCH 01/21] net: slight optimization of addr compare for some modules
Use the recently added and possibly more efficient
ether_addr_equal_unaligned to instead of memcmp.
