I ported this to 3.3.7+ and applied it to my kernel
trees.  It has tested out fine so far, though it did not
actually fix the problem I was having.  That was not
a real leak, just always-growing pending queue length,
probably due to some issue with our version of pktgen.

It is mostly a port-by-hand type of thing since
there are lots of conflicts.  Let me know if you'd
like me to post my version (and plz confirm your
signed-off-by).

Thanks,
Ben
