Errr.... sorry, but at the latest news, TCP was supposed to handle out of order packets and reorder them before sending

Not to mention hashing that almost systematically makes that all packets of the same TCP stream will be sent on the 
same link in an LAG (also on most if not all ECMP implementations).
