OFP has bad behaviour when processing fragment IP packet. There is a double free for odp_packet_t.

After debuging, If found the first free happened on ofp_ip_reass .

And the second free happened again on ofp_packet_input.

Any one has similar issue?

No idea, yet, I may have a different code version.
Is it the last received fragment of the packet?
Is always reproducible?
