Subject: 64bit counters: iproute(netlink) vs ifconfig

Hello,

Just discovered that counters returned by the "ip" tool are truncated:

# ip -s link show bond0
1: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue
     link/ether 00:1d:09:67:6e:2f brd ff:ff:ff:ff:ff:ff
     RX: bytes  packets  errors  dropped overrun mcast
     2485605521 9010211  0       0       0       6
     TX: bytes  packets  errors  dropped carrier collsns
     3023237974 9345397  0       0       0       0

# ifconfig bond0
bond0     Link encap:Ethernet  HWaddr 00:1D:09:67:6E:2F
           inet addr:192.168.152.62  Bcast:192.168.152.255  Mask:255.255.255.0
           inet6 addr: fe80::21d:9ff:fe67:6e2f/64 Scope:Link
           UP BROADCAST RUNNING MASTER MULTICAST  MTU:1500  Metric:1
           RX packets:9010367 errors:0 dropped:351 overruns:0 frame:0
           TX packets:9345521 errors:0 dropped:0 overruns:0 carrier:0
           collisions:0 txqueuelen:0
           RX bytes:2485631020 (2370.4 Mb)  TX bytes:7318232294 (6979.2 Mb)

Is it possible to get 64-bit counters in ip via netlink? Struct 
rtnl_link_stats does not look very optimistic, as it has rx_bytes/tx_bytes 
defined with __u32.

Best regards,
