From: Numan Siddique <nusid...@redhat.com> Normally flow's dl_type will be a valid value. However when a packet is sent to the controller, dl_type is not stored in the 'ofputil_packet_in_private'. When the controller resumes (OFPRAW_NXT_RESUME) the packet, the flow's dl_type will be 0. If the flow's ct_state has valid value, then the 'pkt_metadata_from_flow' neither sets the ct_orig_tuple from the flow nor resets it. This results in invalid value ct_orig_tuple in the pkt_metadata.
This patch handles this situation by checking the dl_type before setting the ct_orig_tuple. If dl_type is 0, it resets it.
