Subject: am79c961a: Use net_device_stats from struct net_device
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=264fd77a67f1a4fe102477d824014459c7ff61f3;p=linux-beck.git

am79c961a: Use net_device_stats from struct net_device

struct net_device has its own struct net_device_stats member, so we can
use this one instead of a private copy in the dev_priv struct.
