Subject: iproute2 showing wrong number of bytes on 64bit architectures.


While investigating the problems reported in Debian bug #199054
(, stating that the RX/TX bytes differ between
ifconfig and ip(route2) I came across this:

include/linux/if_link.h (used in kernel and iproute2 source):
/* The struct should be in sync with struct net_device_stats */
struct rtnl_link_stats
	__u32 ...;
	__u32 ...;
	__u32 ...;
	__u32 ...;

struct net_device_stats
	unsigned long   ...;
	unsigned long   ...;
	unsigned long   ...;
	unsigned long   ...;
	unsigned long   ...;

This will be a problem when unsigned long isn't 32bits, but I guess the
rtnetlink message size is static for good reason. 
Can someone please advise on how to fix this?
