tcpreplay should send the packet as-is ... if wireshark can decode the
packet before sending it with tcpreplay and is unable after you play
with tcpreplay. You can guess that it's tcpreplay fault ... or limitation.
Did you already ask to the tcpreplay maintainers if it can handle your
configuration?
P.S. : You can also send the two traces here to try to see what happened.
