I will fix this.

I will add an option to the fanout, as a flag bit to the setsockopt,
that will cause the fanout to act as a ip_defrag() agent and rehash
the packet once all the fragments arrive.

Since this will operate internally on the clones passed to AF_PACKET,
it will not have any effect on the original packets traversing through
the machine.
