 So, iproute2-2.6.23 with linux-2.6.20.1 ?  I'm always reluctant to
use either kernel headers or versions of iproute which are newer
than the kernel.  You haven't said which headers you used, ideally
they should come from the _patched_ kernel, but changing them means
rebuilding the whole system so I wouldn't do that just for the sake
of it.  Iproute is a different can of worms - I recommend you try an
older version, 2.6.20-070313 in this case.  That doesn't guarantee
to fix this, of course.
