Prev: [PATCH] cs89x0: Use the instance of net_device_stats from net_device.
Next: [PATCH] epic100: Use the instance of net_device_stats from net_device.
From: Kulikov Vasiliy on 5 Jul 2010 08:20
Since net_device has an instance of net_device_stats,
we can remove the instance of this from the adapter structure.
