Hi Cong,

In the act_ct the fragment packets will defrag to a big packet and do conntrack things.

But in the latter filter mirred action, the big packet normally send over the mtu of outgoing device.

So in the act_mirred send the packet should fragment. 

I think this is a bugfix in the net branch the act_ct handle with fragment will always fail.
