Much appreciated.

The action code change is trivial since the dump_stats exists. Located
in cls_api.c in call to copy_stats.
My recomendation is to to not even bother using old API since this is
new code. Go ahead and rip it out and just send TC_STAT2 _only_
Sorry, dont have the energy to do it right now.

Youve heard of the TheLinuxWAY(tm) I hope ;-> Otherwise know as
cutnpaste. One has bug others follow ;->

BTW, you would be submitting the iproute2 patches as well, correct ?
i.e you are not just using your tool to do the testing?
