Prev: [PATCH] davinci_emac: Use the instance of net_device_stats from net_device.
Next: [PATCH] cs89x0: 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.
