[ovs-discuss] Datapath : Mapping a packet with its copy in the slow path

Is it possible in the slow path to map the original packet that is received
by the kernel datapath (via ovs_vport_receive) and copied during the upcall
(via userspace_queue) with its copy that is sent back by ovs-vswitchd after
determining the required actions to be executed by the datapath ?
I'm using tracing tools to track the different states through which a
packet (identified by its skbaddr) may go from the time it is received by
an OVS vport til the time it is sent out by the datapath.
Any idea or comment on how to do this mapping is really appreciated.
