Subject: netlink regression (since 2.6.18)

On a Ubuntu x86_64 machine the command: 
  tc qdisc ls
gets a RTNETLINK error. It looks like some data structure alignment
issue got introduced between 2.6.18 and 2.6.19-rc1 and continues on. 
Since netlink data structure layout is part of the user ABI, we need to go back
and keep compatibility.

Still working out the bisect to find where the problem started.
