The packet sequence doesn't change with higher speeds.   Sounds like
your device inline is introducing enough delay that it is getting
confused when the reply is being received before it is done processing
the request.

I suppose it's also possible that kernel in your tcpreplay box is
buffering the packets and not sending them when tcpreplay actually
sends it.  If that is the case, I'd love to hear more about what
OS/Hardware you're running.

Sounds like Tomahawk.

Again, packet order does not change with speed, unless something
outside of tcpreplay's control is causing delays.  Honestly, I don't
have any intention of adding this functionality to tcpreplay since
tomahawk already does it, but I won't turn down a decent patch either.

Aaron
