commit fb875333c80942455551f690f306a899ceeee5df
    Author: Stephen Hemminger <shemminger@vyatta.com>
    Date:   Wed Jan 7 18:02:53 2009 -0800

    dvb: update network device to current API

    Use internal network_device_stats that exist in network device and
    net_device_ops. Compile tested only.

commit 0eade1f930fa3ba6461b34baf3ed8fa7c4abc40f
    Author: Wang Chen <wangchen@cn.fujitsu.com>
    Date:   Wed Dec 3 21:13:13 2008 -0800

    dvb: Kill directly reference of netdev->priv

    Simply replace netdev->priv with netdev_priv().
