My suspicion is that dhcpd uses netlink to dump the info of the
available links, and due to some bug gets confused with the new 64-bit
statistic netlink attribute being there now.

That shouldn't happen, applications should just ignore the attributes
which they don't understand.

I'll try to find a second to have a look at this.
