Message-ID: <20091007124213.GA30056@serverengines.com>
Date: Wed, 7 Oct 2009 18:12:23 +0530
From: Ajit Khaparde <ajitkhaparde@...il.com>
To: davem@...emloft.net, netdev@...r.kernel.org
Subject: [PATCH net-next-2.6] e1000: Use the instance of net_device_stats
from net_device.
Since net_device has an instance of net_device_stats,
we can remove the instance of this from the adapter structure.
Signed-off-by: Ajit Khaparde <ajitk@...verengines.com>
