As shown in our test results, Flent (which implements the RRUL test) is indeed now capable of tracking the latency experienced by individual TCP flows.  It does not do so at the packet level, but at the socket level.

Of course it is also possible to capture the traffic and analyse the traces offline, if you really do want packet-level detail.
