Hi,

getifaddrs(3) and rtnetlink(7) both refer to struct net_device_stats,
but the actual struct returned is rtnl_link_stats (I noticed this
because using net_device_stats leads to completely bogus values on
64bit).  As far as I can tell struct net_device_stats is used inside the
kernel, but net/core/rtnetlink.c:rtnl_fill_ifinfo() exports that
information as struct rtnl_link_stats in the netlink message.
