From: Kulikov Vasiliy Date: Mon, 5 Jul 2010 02:13:15 +0000 (+0000) Subject: cs89x0: Use the instance of net_device_stats from net_device. X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=661a16ce9da615eb75d1052cbb13b6545f0080b4;p=openwrt%2Fstaging%2Fblogic.git cs89x0: 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: Kulikov Vasiliy Signed-off-by: David S.
