From: Wang Chen <wangchen@...fujitsu.com>
To: David Miller <davem@...emloft.net>
CC: jgarzik@...ox.com, netdev@...r.kernel.org
Subject: [PATCH net-next v2]netdevice: 82596: Convert netdev->priv to netdev_priv
The memory, which pointed by netdev->priv, can be allocated by alloc_etherdev().
We don't need to use __get_free_pages() to get memory.
